Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a vibration-damping shell of a compressor, a compressor assembly and an air conditioner. Background Art

[0002] A conventional vibration-damping shell for a compressor consists of a rigid metal shell and a solid, panel-like vibration-damping and noise-reducing layer, arranged sequentially from the outside inward. The layer is made of foam or a spacer material, and its inner surface forms a large mating surface that can contact and mate with the surface of the compressor body. Multiple vibration-damping shells can be spliced together along the circumference of the compressor body, forming a single shell that surrounds the compressor body. Naturally, the shell avoids any structures connected to the compressor body's outer periphery.

[0003] The problem with the existing vibration-damping shell is that since the compressor body, the solid plate-shaped vibration-damping and noise-reducing layer and the rigid shell are all in large-area contact and fit, this arrangement causes more vibration of the compressor body to be transmitted to the rigid shell, affecting the vibration-damping and noise-reducing effect. Utility Model Content

[0004] A first object of the present invention is to provide a vibration-damping shell for a compressor that improves vibration and noise reduction effects.

[0005] A second object of the present invention is to provide a compressor with improved vibration reduction and noise reduction effects.

[0006] A third object of the present invention is to provide an air conditioner with improved vibration reduction and noise reduction effects.

[0007] The first purpose of the present invention is to provide a vibration-damping shell of a compressor; the vibration-damping shell also includes a plurality of vibration-damping bodies arranged in an array, the vibration-damping bodies are hollow structures made of elastic material and are provided with through holes; the inner side of the shell is provided with a plurality of mounting positions arranged along the array and two relatively arranged snap-fit structures corresponding to each mounting position; the vibration-damping body is installed in the mounting position, and the two ends of the through hole of the vibration-damping body are respectively engaged with the two snap-fit structures corresponding to the mounting position.

[0008] As can be seen from the above scheme, compared to the background technology, the present invention adds a hollow vibration damper made of elastic material. This allows the rigid outer shell to not only work in conjunction with the damper to dampen vibrations such as those caused by the compressor's rotation and swing, but the elastic hollow damper effectively attenuates compressor vibrations by increasing its deformation, converting kinetic energy into internal energy and dissipating it. This significantly reduces the vibration transmitted from the compressor to the vibration- and noise-reducing rigid shell, and also provides sound insulation, working in conjunction with the sound-absorbing material layer to reduce compressor noise, thereby enhancing the vibration and noise reduction effects.

[0009] A further solution is that the outer shell includes an inner surface, and the mounting position is recessed in the inner surface; the vibration damping body includes a first surface and a second surface arranged opposite to each other; the first surface is an outward convex arc surface and the first surface matches the inner surface of the mounting position, and / or the second surface is an inward concave arc surface and the second surface matches the surface of the compressor body.

[0010] As can be seen from the above, on the vibration damping body, the curvature of the second surface close to the compressor is consistent with the surface of the compressor body, ensuring close contact with the compressor casing. The first surface close to the rigid shell has an outward convex arc that is consistent with the curvature of the groove of the mounting position, which can increase the contact area between the rigid shell and ensure sufficient contact, thereby further improving the vibration damping effect.

[0011] A further solution is that the outer shell includes a reinforcing rib network protruding from the inner surface, the reinforcing rib network includes circumferential ribs extending along the circumference of the compressor, and the snap-fit structure is connected to the circumferential ribs.

[0012] In another further solution, the reinforcing rib network further includes axial ribs extending along the axial direction of the compressor, and the plurality of axial ribs are staggered and connected with the plurality of circumferential ribs.

[0013] As can be seen from the above, first, a network of reinforcing ribs is provided in the rigid shell to improve the overall rigidity; further, multiple axial ribs and multiple circumferential ribs are staggered and connected to further enhance the strength of the network of reinforcing ribs; on the other hand, after a network of reinforcing ribs is provided on the inner side of the shell, the inner layer of sound-absorbing material is connected to the network of reinforcing ribs and no longer contacts and cooperates with a large area of the inner surface of the shell, which can reduce sound transmission and enhance the noise reduction effect.

[0014] A further solution is that the mounting position is set between two adjacent circumferential ribs; the locking structure is a locking column, which extends from the circumferential rib along the axial direction of the compressor toward its corresponding mounting position, and the two locking columns corresponding to the same mounting position have opposite extension directions, and the locking column is inserted into the through hole.

[0015] As can be seen from the above, the circumferential ribs can also serve as a structure for limiting the vibration damping body and a basis for setting the engaging structure, thereby improving the reliability of the installation of multiple vibration damping bodies.

[0016] Another further solution is that the shell extends more than 180 degrees along the circumference of the compressor and forms an avoidance fracture at a circumferential position.

[0017] As can be seen from the above, under this setting, the cross-section of the shell is C-shaped, which can avoid the compressor fluid storage tank.

[0018] A further solution is to provide an avoidance gap at the first axial end of the shell, wherein the avoidance gap passes through the inner and outer sides of the shell and is open along the axial direction of the shell.

[0019] As can be seen from the above, the lower part of the shell is a circumferentially discontinuous structure, which can avoid the compressor legs and foot pads.

[0020] A further solution is that a connecting portion protruding outward is provided at the first axial end of the housing, and a connecting hole is provided at the connecting portion.

[0021] As can be seen from the above, the connecting portion serves as the connecting portion at the bottom of the rigid shell that cooperates with the base of the external unit. A corresponding number of connecting holes are opened on the connecting portion for being threadedly connected and fixed with the base of the external unit.

[0022] Another further solution is that a plurality of vibration dampers are arranged along the circumferential direction of the compressor, and a plurality of vibration dampers are arranged along the axial direction of the compressor.

[0023] As can be seen from the above, the multiple vibration dampers arranged in the cylindrical array achieve all-round vibration reduction of the circumferential rotation vibration and swing vibration of the upper, middle and lower parts of the compressor.

[0024] A further solution is to further include a sound-absorbing material layer arranged on the inner side of the shell, the sound-absorbing material layer is provided with a communication position, the communication position is connected between the installation position and the inner side of the sound-absorbing material layer, and the vibration damping body is located at the communication position; the sound-absorbing material layer includes a plurality of sound-absorbing parts arranged at intervals along the axial direction of the compressor, and the communication position is formed between two adjacent sound-absorbing parts.

[0025] As can be seen from the above, this arrangement is conducive to leaving space around the entire circumference of multiple groups of vibration dampers arranged along the circumferential direction to facilitate layout. In addition, under this arrangement, the outer contour of the sound absorbing member is simple and easy to form and manufacture.

[0026] A further solution is that at least one sound absorbing member is annular; and / or the plurality of sound absorbing members include an end sound absorbing member connected to the second axial end of the shell, and the end sound absorbing member includes an axial stop.

[0027] As can be seen from the above, the appropriate shape enables the sound absorbing member to fully utilize the space to achieve better sound absorption and noise reduction effects, and / or the end sound absorbing member also absorbs and reduces the noise of the top of the compressor.

[0028] The second object of the present invention is to provide a compressor comprising a body and a vibration-damping shell sleeved outside the body, wherein the vibration-damping shell adopts the above-mentioned vibration-damping shell.

[0029] The third object of the present invention is to provide an air conditioner comprising the above-mentioned compressor. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figures 1 to 3 The compressor of this embodiment includes a compressor body 91, a vibration-damping pad 93, a liquid storage tank 94 and a vibration-damping shell of the present invention.

The sound-absorbing material layer 2 includes three sound-absorbing parts: a first sound-absorbing part 21, a second sound-absorbing part 22 and an end sound-absorbing part 23.

[0043] See also Figure 4The vibration damper 3 is a hollow structure made of rubber and is provided with a through hole 30. The vibration damper 3 is cylindrical, and the through hole 30 runs through both ends of the length of the vibration damper 3 and is open at both ends. The outer peripheral surface of the vibration damper 3 includes a first surface 31 and a second surface 32 that are oppositely arranged. The first surface 31 is an outward convex arc surface and the first surface 31 and the mounting position 110 ( Figure 9 The second surface 32 is a concave arc surface and matches the surface of the body 91.

[0044] See also Figures 5 to 7 The first sound absorbing member 21, the second sound absorbing member 22, and the end sound absorbing member 23 are all made of sound-absorbing materials, such as foam or fiber, that exhibit significant shape change and recovery capabilities. Each of the first sound absorbing member 21, the second sound absorbing member 22, and the end sound absorbing member 23 is annular. To accommodate and better utilize space, the first sound absorbing member 21 is provided with a protruding portion 211, while the second sound absorbing member 22 is provided with a notched portion 221. More specifically, the end sound absorbing member 23 is connected to the second axial end of the housing 1, i.e., the upper end of the housing 1, and includes an axial stop 231 that can axially block the housing 91.

[0045] See also Figure 8 and combined Figure 1 and Figure 2 The outer shell 1 is made of a rigid metal material. The outer shell 1 made of a rigid material is an acoustically rigid structure and can fully reflect sound. The outer shell 1 extends more than 180 degrees along the circumference of the compressor and forms an avoidance fracture 101 at a circumferential position. The cross-section of the outer shell 1 is C-shaped, which can avoid the liquid storage tank 94; three avoidance notches 102 are set at the first axial end of the outer shell 1. The avoidance notches 102 pass through the inner and outer sides of the outer shell 1 and are open along the axial direction of the outer shell 1. The lower end of the outer shell 1 is a circumferentially discontinuous structure, which can avoid the vibration-damping foot pad 93. The lower end of the outer shell 1 is provided with a connecting portion 19 protruding outward, and the connecting portion 19 is provided with a connecting hole 190. The connecting portion 19 serves as the connecting portion of the bottom of the rigid outer shell 1 that cooperates with the base of the external unit. The connecting portion 19 is supported on the base 92. The bolt 4 passes through the connecting hole 190 and is connected to the base 92 to realize the upright fixation of the vibration-damping shell.

[0046] Recombination Figure 9The outer shell 1 includes a reinforcing rib network 12 protruding from the inner surface 11. The reinforcing rib network 12 includes circumferential ribs 121 extending along the circumference of the compressor and axial ribs 122 extending along the axial direction of the compressor. Multiple axial ribs 122 are interlaced and connected with multiple circumferential ribs 121 to form the reinforcing rib network 12. The circumferential ribs 121 are not arranged equidistantly in the axial direction of the compressor. Instead, two circumferential ribs 121 are grouped together. The axial spacing between the two circumferential ribs 121 in each group is relatively small, while the axial spacing between adjacent groups of circumferential ribs 121 is relatively large. Furthermore, this embodiment includes three groups of six circumferential ribs 121.

[0047] The inner side of the housing 1 is provided with a plurality of mounting positions 110 arranged along a cylindrical array. The cylindrical array of mounting positions 110 includes three circles of mounting positions 110 spaced apart along the axial direction of the compressor, and each circle of mounting positions 110 includes a plurality of mounting positions 110 arranged circumferentially. The mounting positions 110 are recessed into the inner surface 11, and the recessed positions have an inner surface with a concave arc profile.

[0048] The three circles of mounting positions 110 are respectively arranged at three groups of axial ribs 122. The multiple mounting positions 110 in each circle of mounting positions 110 are arranged between two closely spaced axial ribs 122 in the corresponding group of axial ribs 122. The housing 1 is also provided with two opposing engaging structures corresponding to each mounting position 110. In this embodiment, the engaging structures are engaging posts 13 with a roughly semicircular cross-sectional area. The engaging posts 13 extend from the circumferential ribs 121 along the axial direction of the compressor toward their corresponding mounting position 110. The two engaging posts 13 corresponding to the same mounting position 110 extend in opposite directions.

[0049] Recombination Figure 10 and Figure 11 The vibration damper 3 is placed in the mounting position 110 and protrudes inwardly from the inner side of the housing 1. The two ends of the through hole 30 of the vibration damper 3 are respectively inserted into and engaged with the two engaging columns 13 corresponding to the mounting position 110. Figure 4 Furthermore, the first surface 31 of the vibration damper 3 matches the inner surface of the mounting position 110, and the second surface 32 of the vibration damper 3 faces the mounting position of the compressor body 91. Furthermore, the multiple vibration dampers 3 mounted in each mounting position 110 are also arranged in a cylindrical array.

[0050] See also Figure 2 and Figure 3The first sound absorbing member 21, the second sound absorbing member 22, and the end sound absorbing member 23 are spaced apart along the axial direction of the compressor. Surrounding communication positions 20 are formed between the first sound absorbing member 21 and the second sound absorbing member 22, and between the second sound absorbing member 22 and the end sound absorbing member 23. In addition, a communication position 20 is further formed below the first sound absorbing member 21. The communication position 20 is a position on the sound absorbing material layer 2 where the sound absorbing material is not provided and can be used to arrange the mounting position 110 and the vibration damping body 3. The communication position 20 connects the mounting position 110 and the inner side of the sound absorbing material layer 2, and the vibration damping body 3 installed in the mounting position 110 is also located in the communication position 20.

[0051] When assembling the vibration damping housing, first install the vibration damper 3 into the mounting position 110, and simultaneously install the first sound absorbing member 21, the second sound absorbing member 22, and the end sound absorbing member 23 onto the compressor body 91. Then, the outer shell 1, with the vibration damper 3 installed, is axially inserted downward from the top of the body 91 into position, completing the installation of the vibration damping housing. Because the first sound absorbing member 21, the second sound absorbing member 22, and the end sound absorbing member 23 can deform to a large extent, they can avoid interference with the multiple vibration dampers 3 during downward installation. Finally, the vibration damping housing is connected to the base 92 via the vibration damping housing.

[0052] Mainly, the utility model adds a vibration-damping body 3 with a hollow structure made of elastic material. The rigid outer shell 1 can not only cooperate with the vibration-damping body 3 to reduce the vibration of the compressor such as rotation and swing, but the elastic hollow vibration-damping body can effectively attenuate the vibration of the compressor by increasing the deformation, and convert the kinetic energy into internal energy and dissipate it. At the same time, it greatly reduces the vibration transmitted by the compressor to the vibration-damping and noise-reducing rigid shell, and also plays a sound insulation role, and cooperates with the sound-absorbing material layer 2 to reduce the noise of the compressor, thereby improving the vibration-damping and noise-reducing effect.

[0053] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
