Referring to fig. 1, an outdoor unit of an air conditioner according to an embodiment of the present invention includes a base plate 30 and a compressor assembly 20. Specifically, the base plate 30 is a base structure of the outdoor unit of the air conditioner, and supports components including the compressor assembly 20. In some embodiments, the compressor assembly 20 includes a compressor 21, an accumulator 22, and a four-way valve 23, wherein the compressor 21 and the accumulator 22 are fixedly mounted on the chassis 30, and the four-way valve 23 is disposed above the compressor 21 and is connected to the compressor 21 and the accumulator 22 through a first exhaust pipe 24 and a second exhaust pipe 25, respectively.
Referring to fig. 1, the outdoor unit of the present embodiment further includes a sound insulation assembly 10, wherein the sound insulation assembly 10 is mounted on the base plate 30 and wraps the outer surface of the compressor assembly 20, so as to effectively isolate noise of the compressor assembly 20, and reduce noise of the outdoor unit of the air conditioner.
Referring to fig. 2 and 3, in the soundproof assembly 10 according to an embodiment of the present invention, the soundproof assembly 10 is applied to a compressor assembly 20, the compressor assembly 20 includes a compressor 21 and an accumulator 22, and the soundproof assembly 10 covers outer surfaces of the compressor 21 and the accumulator 22. Specifically, the acoustic barrier assembly 10 includes a foam layer 100, an acoustic barrier layer 200, and an acoustic roof 300. The foam material layer 100 is at least partially attached to the sound insulation layer 200, and the foam material layer 100 isolates medium and high frequency noise radiated from the compressor 21 and also has a noise reduction effect on the medium and low frequency noise.
The foam material layer 100 may be entirely covered on the inner wall of the sound insulation layer 200 or the outer wall of the sound insulation layer 200, or entirely sandwiched in the sound insulation layer 200. For example, the foam layer 100 and the soundproof layer 200 are wrapped around the outer surface of the compressor assembly 20 and attached to each other. In another embodiment, the foam material layer 100 may be partially covered on the inner wall or the outer wall of the soundproof layer 200, or partially covered in the soundproof layer 200. For example, the sound insulation layer 200 surrounds the outer surface of the compressor element 20, and the foam layer 100 is only partially attached to the sound insulation layer 200. It is understood that the foam material layer 100 may be directly attached to the soundproof layer 200 through a foaming process, so that the foam material layer 100 and the soundproof layer 200 form an integral structure. In this embodiment, the sound insulation layer 200 is used to support the foam material layer 100, so that the foam material layer 100 and the sound insulation layer 200 are attached to each other to form a stable integrated installation structure, and the integrated installation structure can be integrally sleeved into the compressor assembly 20 for installation, which is convenient to install and high in production efficiency; in addition, the soundproof layer 200 has a capability of isolating medium and high frequency noise radiated from the compressor 21.
It should be further noted that the sound insulation layer 200 and the foam material layer 100 enclose to form a sound insulation chamber 400, and the compressor 21 and the reservoir 22 are located in the sound insulation chamber 400, so that medium-high frequency noise radiated from the compressor 21 and the reservoir 22 can be effectively isolated, and a certain isolation effect is provided for the medium-low frequency noise. In addition, the soundproof top cover 300 is positioned above the soundproof cavity 400, so that the soundproof cavity 400 can be sealed and soundproof, noise generated by the compressor 21 and the liquid reservoir 22 is prevented from being transmitted upwards, and the noise reduction effect of the soundproof assembly 10 is further improved.
In some embodiments, referring to fig. 1 and 3, the four-way valve 23 is installed above the soundproof top cover 300, so that the soundproof top cover 300 is penetrated with a first installation hole 310 and a second installation hole 320 respectively engaged with the first exhaust pipe 24 and the second exhaust pipe 25; moreover, in order to improve the installation efficiency of the soundproof top cover 300, a first installation groove 330 is opened between the first installation hole 310 and the outer edge of the soundproof top cover 300, and a second installation groove 340 is opened between the second installation hole 320 and the outer edge of the soundproof top cover 300, so that the first exhaust pipe 24 can be inserted from the first installation groove 330 and positioned through the first installation hole 310, the second exhaust pipe 25 can be inserted from the second installation groove 340 and positioned through the second installation hole 320 when the soundproof top cover 300 is installed, and thus the installation is completed. Further, first mounting groove 330 and second mounting groove 340 set up parallel to each other, can realize that first blast pipe 24 and second blast pipe 25 penetrate the installation in step, further improve the efficiency of installation.
Referring to fig. 4, in the sound insulation assembly 10 of the present embodiment, the inner wall of the foam material layer 100 surrounds the outer surface of the compressor assembly 20, and the sound insulation layer 200 surrounds and is attached to the outer wall of the foam material layer 100, so that noise generated during the operation of the compressor assembly 20 is absorbed and filtered by the foam material layer 100, and then is further absorbed by the sound insulation layer 200, which can isolate most of the noise radiated from the compressor assembly 20, thereby effectively reducing the noise. Specifically, foaming material layer 100 is attached in puigging 200 inner wall through the foaming process, and puigging 200 is used for supporting foaming material layer 100 to make mutual attached foaming material layer 100 and puigging 200 form stable integrative mounting structure, can install in whole emboliaing compressor unit 20 with integrative mounting structure, its installation is convenient, production efficiency is high.
Referring to fig. 4, the inner wall of foam layer 100 at least partially conforms to the outer surface of compressor 21 and reservoir 22. It can be understood that, compressor unit 20 is in the operation, compressor 21 and reservoir 22 can produce the vibration, foam material layer 100 inner wall and compressor 21 and reservoir 22 closely laminate, can be with vibration transmission to foam material layer 100, foam material layer 100 can play certain inhibiting action to the vibration, thereby play buffering vibration damping's effect to compressor 21 and reservoir 22, prevent that the vibration from transmitting to four-way valve 23 and pipe fitting (for example first blast pipe 24 and second blast pipe 25), chassis 30 or on the sheet metal component on every side, avoid the pipe fitting to break because of fatigue, and can reduce compressor unit 20's operating noise.
Referring to fig. 3, the foam material layer 100 is formed with a plurality of sound absorbing holes 110 penetrating through the foam material layer 100, so that the sound insulation effect of the foam material layer 100 can be further improved. Specifically, when the low-and-medium-frequency noise passes through the sound absorption hole 110 of the foam material layer 100, the sound absorption hole 110 can break up the sound wave, so that the energy of the noise is dissipated, and the noise reduction effect is achieved, therefore, the sound absorption hole 110 has a good sound insulation effect on the low-and-medium-frequency noise, and the noise reduction capability of the sound insulation component 10 is better.
It should be noted that the porous material formed by the plurality of sound absorption holes 110 has a sound absorption function mainly because sound absorption mechanisms such as intrinsic damping and viscous loss on the surface of the gap exist inside the porous material; when sound waves are incident to the surface of the porous material, one part of the sound waves can enter the material in different modes, and the other part of the sound waves are reflected out of the surface of the material; when the part of sound wave entering the material is transmitted in the holes, the air is driven to move to generate a viscous and frictional effect, meanwhile, the temperature of the air in some small holes is increased when the air is compressed, and the sound energy is gradually converted into heat energy to be dissipated by adding the heat conduction effect of the material, and the conversion process is irreversible, so that the material generates a sound absorption effect.
In some embodiments, the thickness of the foam layer 100 is in the range of 15mm to 22mm, which can provide better sound insulation. For example, the thickness of the foam material layer 100 may be 15mm, 20mm, 22mm, etc., and it is understood that the thickness of the foam material layer 100 is in the range of 15mm to 22mm, and the sound insulation effect is better as the thickness increases, and in actual use, the thickness of the foam material layer 100 is selected according to the installation space of the outdoor unit of the air conditioner, and the thickness of the combined sound insulation layer 200. In addition, when the thickness of the foam material layer 100 is excessively large, the soundproof effect of the foam material layer 100 is not significantly increased, and a waste of an installation space of the outdoor unit of the air conditioner may be caused. In some embodiments, the aperture of the sound absorption hole 110 is in the range of 6mm to 14mm, and the distance between adjacent sound absorption holes 110 is in the range of 10mm to 20mm, so as to achieve a good sound absorption effect. For example, the aperture of the sound absorbing hole 110 may be 10mm and the pitch may be 12 mm. It is understood that the pore size of the sound absorbing holes 110 of the foam material layer 100 and the distance between the sound absorbing holes 110 may be the same or different, and may be selected according to the actual sound insulation requirement and the production condition. In addition, the shape of the sound absorbing hole 110 may be circular, hexagonal, honeycomb, or the like, and the shape of the sound absorbing hole 110 of the foam material layer 100 may be uniform or non-uniform, and may be specifically selected according to actual sound insulation needs and production conditions.
Referring to fig. 5, in the sound insulation assembly 10 of the present embodiment, the sound insulation layer 200 surrounds the outer surface of the compressor assembly 20, and the foam material layer 100 surrounds and is attached to the outer wall of the sound insulation layer 200, so that noise generated during the operation of the compressor assembly 20 is absorbed by the sound insulation layer 200, and then is further absorbed and filtered by the foam material layer 100, which can isolate most of the noise radiated from the compressor assembly 20, thereby effectively reducing the noise. Specifically, foaming material layer 100 is attached in puigging 200 outer wall through the foaming technology, and puigging 200 is used for supporting foaming material layer 100 to make mutual attached foaming material layer 100 and puigging 200 form stable integrative mounting structure, can install in whole emboliaing compressor unit 20 with integrative mounting structure, its installation is convenient, production efficiency is high. Further, puigging 200 closely laminates in compressor unit 20 for noise barrier 10 can stabilize the suit in compressor unit 20's surface, avoids taking place the dislocation between compressor unit 20, thereby produces the installation clearance, leads to the emergence of lou.
In some of these embodiments, the foam layer 100 is a foam. The foamed plastic mainly comprises Polyurethane (PUR), Polystyrene (PS), polyvinyl chloride (PVC), Polyethylene (PE), phenolic resin (PF) and the like. For example, the foam material layer 100 of the embodiment is made of a polyurethane foam material, which has a better sound insulation effect and a lower production cost than other foam materials. It is understood that the type of the foam plastic used in the foam material layer 100 may be consistent, or different types of materials may be used in combination, and the type of the foam plastic may be selected according to the sound insulation requirement and the production condition of the actual product.
In some of these embodiments, the sound-insulating layer 200 can be at least one of sound-insulating cotton, knitted felt, leather, or linen. For example, the soundproof layer 200 may be made of soundproof cotton, or of knitted felt, or of leather, or of linen. Further, the soundproof layer 200 may be a combination of two materials of soundproof cotton, knitted felt, leather or linen material, or a combination of a plurality of materials.

In some of these embodiments, further, the acoustical layer 200 has a thickness in a range from 4mm to 8 mm. For example, the thickness of the soundproof layer 200 may be 4mm, 6mm, 8mm, etc., and it is understood that the thickness of the soundproof layer 200 is in a range of 4mm to 8mm, and the soundproof effect is better as the thickness increases, and in actual use, the thickness of the soundproof layer 200 is selected according to the installation space of the outdoor unit of the air conditioner and the thickness of the combined foam material layer 100. In addition, when the thickness of the soundproof layer 200 is excessively large, the soundproof effect of the soundproof layer 200 is not significantly increased, and the installation space of the outdoor unit of the air conditioner is wasted.
In some embodiments, the acoustic cap 300 is made of acoustic cotton, knitted felt, or the like. For example, the soundproof top cover 300 can be made of soundproof cotton, or knitted felt, or a combination of soundproof cotton and knitted felt.
