[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] In related technologies, existing air conditioners generally include a casing, a compressor, and a soundproof cover. Both the compressor and the soundproof cover are located inside the casing, with the soundproof cover covering the compressor to reduce the noise during compressor operation. The compressor is generally connected to the casing via vibration-damping pads, while the contact between the soundproof cover and the casing is a hard contact. Vibrations generated during compressor operation are easily transmitted to the soundproof cover, resulting in poor noise reduction performance of the air conditioner.

[0037] Reference Figures 1 to 5 According to an embodiment of the present invention, an air conditioner includes a housing, a compressor 200, a soundproof cover assembly 300, and a vibration damping assembly 400. The housing has a base plate 100. The compressor 200 is disposed inside the housing. The soundproof cover assembly 300 is disposed inside the housing and covers the compressor 200. The vibration damping assembly 400 includes a vibration damping member 410 and vibration damping pads 420 disposed on the vibration damping member 410. Both the vibration damping member 410 and the vibration damping pads 420 are elastic. The compressor 200 is mounted on the base plate 100 via the vibration damping pads 420, and the soundproof cover assembly 300 is mounted on the base plate 100 via the vibration damping member 410. By providing the vibration damping pads 420 and the vibration damping member 410, on the one hand, the vibration of the compressor 200 during operation can be reduced to be transmitted to the base plate 100, and on the other hand, the vibration of the base plate 100 can be reduced to be transmitted to the soundproof cover assembly 300, thereby improving the noise reduction effect of the air conditioner.

[0038] Specifically, when the compressor 200 is working, the vibration generated by the compressor 200 is transmitted to the base plate 100 through the vibration damping pads 420. The vibration of the base plate 100 is transmitted to the soundproof cover assembly 300 through the vibration damping component 410. Since both the vibration damping pads 420 and the vibration damping component 410 are elastic, they can reduce the transmission of vibration from the compressor 200 to the base plate 100 and also reduce the transmission of vibration from the base plate 100 to the soundproof cover assembly 300, thereby improving the noise reduction effect of the air conditioner.

[0039] It should be noted that the compressor 200 can be a rotary compressor 200 or a reciprocating compressor 200, etc., and there is no restriction here.

[0040] It should be noted that the compressor 200 is provided with two side-by-side spaced legs 210, each with a mounting hole at both ends. Four vibration damping pads 420 are provided accordingly. The end of the vibration damping pad 420 away from the vibration damping component 410 passes through the corresponding mounting hole and abuts against the leg 210, which facilitates the installation of the compressor 200.

[0041] It should be noted that the vibration damping pad 420 is provided with a through hole 421. The through hole 421 passes through the vibration damping pad 420 in the vertical direction. The bracket 210 is connected to the base plate 100 by fasteners, such as bolts or screws. The fasteners pass through the through hole 421 to achieve a stable connection between the base plate 100 and the compressor 200, which facilitates the installation or disassembly of the compressor 200, so as to facilitate the inspection and maintenance of the compressor 200.

[0042] Reference Figures 5 to 7 In some embodiments of this utility model, the vibration damping component 410 is provided with a plurality of default holes 411, which are arranged at intervals around the outer periphery of the vibration damping pad 420, thereby saving material costs of the vibration damping component 400 and reducing the production and manufacturing costs of the air conditioner.

[0043] Specifically, along the vertical direction, the default hole 411 penetrates the vibration damper 410, and along the axial direction of the vibration damping pad 420, multiple default holes 411 are arranged at intervals around the outer periphery of the vibration damping pad 420, which can save the material cost of the vibration damping assembly 400 and reduce the production and manufacturing cost of the air conditioner.

[0044] It should be noted that the absence of a hole does not necessarily mean that the vibration damper 410 does not need to pass through; this is not a restriction.

[0045] Reference Figures 5 to 7 In some embodiments of this utility model, the vibration damping member 410 has a groove 412 on the side away from the base plate 100. The bottom wall of the groove 412 is spaced apart from the soundproof cover assembly 300, so that there is a gap between the soundproof cover assembly 300 and the bottom wall of the groove 412. This can reduce the contact area between the soundproof cover assembly 300 and the vibration damping member 410, thereby reducing the vibration of the base plate 100 transmitted to the soundproof cover assembly 300 and improving the soundproofing effect of the air conditioner.

[0046] Specifically, the groove 412 is located on the side of the vibration damper 410 away from the base plate 100, and the opening of the groove 412 is located on the side of the vibration damper 410 away from the base plate 100. When the silencer assembly 300 is installed, the silencer assembly 300 abuts against the periphery of the opening of the groove 412, so that there is a gap between the silencer assembly 300 and the bottom wall of the groove 412, which can reduce the contact area between the silencer assembly 300 and the vibration damper 410, thereby reducing the vibration of the base plate 100 transmitted to the silencer assembly 300 and improving the noise reduction effect of the air conditioner.

[0047] It should be noted that one side of the groove 412 extends through the sidewall of the default hole 411 in the width direction, and the other side of the groove 412 extends through the outer peripheral surface of the damper 410, which facilitates the machining of the groove 412, but will not be described in detail here.

[0048] Reference Figures 5 to 7In some embodiments of this utility model, multiple grooves 412 are provided, and the multiple grooves 412 are arranged at intervals along the circumference of the vibration damper 410, which can increase the number of grooves 412 to further reduce the contact area between the soundproof cover assembly 300 and the vibration damper 410, thereby improving the soundproofing effect of the air conditioner.

[0049] Reference Figure 5 , Figure 8 In some embodiments of this utility model, the outer peripheral surface of the vibration damper 410 is provided with a deformation groove 413. The deformation groove 413 extends along the circumference of the vibration damper 410, which can reduce the structural strength of the vibration damper 410 in the vertical direction, thereby increasing the deformation of the vibration damper 410 in the vertical direction, thereby absorbing the vibration transmitted from the base plate 100 to the soundproof cover assembly 300, and improving the soundproofing effect of the air conditioner.

[0050] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the noise-absorbing cover assembly 300 includes a peripheral wall plate 310 and a cover plate 320 connected to the peripheral wall plate 310. The peripheral wall plate 310 and the cover plate 320 together define a noise-absorbing cavity. The compressor 200 is housed in the noise-absorbing cavity, and the periphery of the opening of the peripheral wall plate 310 is connected to the vibration damping member 410. The noise-absorbing cavity can absorb the noise generated by the vibration of the compressor 200, so as to improve the noise reduction effect of the air conditioner.

[0051] Reference Figure 2 , Figure 6 In some embodiments of this utility model, a positioning structure is provided between the vibration damper 410 and the base plate 100 to position the vibration damper 410 so as to facilitate the installation of the vibration damper 410.

[0052] Reference Figure 2 , Figure 6 In some embodiments of this utility model, the positioning structure includes a positioning groove 414 provided on the vibration damper 410 and a positioning protrusion 110 provided on the base plate 100. The positioning protrusion 110 is accommodated in the positioning groove 414 and can position the vibration damper 410 so as to facilitate the installation of the vibration damper 410.

[0053] Specifically, there are two positioning protrusions 110 and two corresponding positioning grooves 414. When installing the vibration damping component 400, the positioning protrusions 110 are accommodated in the corresponding positioning grooves 414 and can abut against the side wall of the corresponding positioning grooves 414, so as to position the vibration damping component 410 for easy installation.

[0054] It should be noted that the positions of the positioning protrusion 110 and the positioning groove 414 can be interchanged. That is, the positioning protrusion 110 can be located on the vibration damper 410, while the positioning groove 414 can be located on the base plate 100. This can also position the vibration damper 410. No restrictions are imposed here.

[0055] As another implementation, the positioning structure can also be a structure in which a positioning pin and a positioning hole cooperate. One of the positioning pin and the positioning hole is provided on the base plate 100, and the other is provided on the vibration damper 410. The positioning pin is accommodated in the positioning hole, which can also position the vibration damper 410. No limitation is made here.

[0056] Reference Figure 5 , Figure 6 In some embodiments of this utility model, the vibration damping pad 420 and the vibration damping component 410 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the vibration damping component 400.

[0057] Specifically, the vibration damping pad 420 and the vibration damping component 410 can be integrally molded by injection molding, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the vibration damping component 400.

[0058] As another implementation, the vibration damping pad 420 and the vibration damping component 410 can also be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, ultrasonic welding or laser welding.

[0059] It should be noted that by connecting the vibration damping pad 420 to the vibration damping component 410, the relative position of the vibration damping component 410 and the compressor 200 can be positioned while installing the vibration damping pad 420, thereby positioning the relative position of the vibration damping component 410 and the soundproof cover assembly 300. There is no need to assemble the vibration damping pad 420 and the vibration damping component 410 separately, which can improve the assembly efficiency of the vibration damping assembly 400. No limitation is made here.

[0060] In some embodiments of this utility model, both the vibration damping pad 420 and the vibration damping component 410 are made of rubber. Rubber has advantages such as high elasticity, wear resistance, and heat resistance, which can not only ensure the service life of the vibration damping component 400, but also absorb the vibration generated when the compressor 200 is working, thereby improving the noise reduction effect of the air conditioner.

[0061] In some embodiments of this utility model, the housing further includes a side wall panel and a top plate. The bottom plate 100 and the top plate are arranged in the vertical direction. The side wall panel is disposed between the bottom plate 100 and the top plate. The side wall panel, the top plate, and the bottom plate 100 enclose a receiving cavity. The compressor 200, the silencer assembly 300, and the vibration damping assembly 400 are all housed in the receiving cavity, which can protect the compressor 200.

[0062] In some embodiments of this utility model, the air conditioner further includes an evaporator and a condenser. A partition is provided inside the housing, which can divide the receiving cavity into a first space and a second space. The condenser and the compressor 200 are both located in the first space, and the evaporator is located in the second space. Both the evaporator and the condenser are connected to the compressor 200 to ensure that the air conditioner can operate normally.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
