[0037] Portable air conditioners are portable and can be placed anywhere, making them more convenient to use. Currently, the compressor is located in the indoor unit of both portable and split-type air conditioners. However, the compressor generates considerable noise during operation, which can affect the user experience.

[0038] At present, the general control measure for noise is to simply wrap a layer of sound insulation cotton around the compressor cylinder, but the seal is not tight and the sound leakage area is large, which makes the noise reduction effect of this method limited.

[0039] The utility model provides a noise reduction structure.

[0040] See also Figure 1 and Figure 2 In one embodiment of the present invention, the noise reduction structure includes a bracket 100 and a soundproof cover 500, and the bracket 100 is hollowed out; the soundproof cover 500 is installed on the bracket 100 to form a receiving chamber 101 for receiving the compressor 600.

[0041] It is understandable that the compressor 600 will generate vibration and noise during operation. The soundproof cover 500 is arranged outside the compressor 600, which can reduce the outward propagation of the working noise of the compressor 600 and reflect the noise as much as possible inside the soundproof cover 500. The soundproof cover 500 blocks and absorbs the noise, thereby isolating the working noise of the compressor 600 from the surrounding air. The soundproof cover 500 is installed on the bracket 100, and the bracket 100 provides an installation support position for the soundproof cover 500. Specifically, the soundproof cover 500 can be installed on the inside or outside of the bracket 100. The bracket 100 is hollowed out, so that the soundproof cover 500 on the bracket 100 can be arranged face to face with the compressor 600, so that the soundproof cover 500 can more directly block and absorb noise.

[0042] In one embodiment, the volume of the receiving chamber 101 enclosed by the bracket 100 and the soundproof cover 500 is relatively large. Thus, on the one hand, due to the larger volume of the receiving chamber 101, more materials are used for the soundproof cover 500. The more materials used for the soundproof cover 500, the more sound energy dissipated. On the other hand, the large volume of the receiving chamber 101 can accommodate the body of the compressor 600 and the pipes connected to the body, and wrapping the pipes can reduce the vibration noise radiation of the pipes. On the other hand, the provision of the bracket 100 facilitates the formation of a sealed cavity by the soundproof cover 500, which improves the sealing of the receiving chamber 101, thereby reducing sound diffraction and leakage, thereby increasing the noise reduction amount and improving the noise reduction effect.

[0043] The technical solution of the present invention is to provide a bracket 100 and a soundproof cover 500 in a noise reduction structure, wherein the bracket 100 is hollowed out and the soundproof cover 500 is mounted on the bracket 100 to form a receiving chamber 101 for accommodating the compressor 600. In this way, on the one hand, the hollowing out of the bracket 100 allows the soundproof cover 500 and the compressor 600 to face each other, so that the soundproof cover 500 can block and absorb noise; on the other hand, the provision of the bracket 100 improves the sealing of the receiving chamber 101, thereby reducing sound leakage, improving the noise reduction effect of the compressor 600, and further enhancing the user comfort of the air conditioner.

[0044] In an embodiment of the present invention, the soundproof cover 500 includes soundproof cotton 200 , which is wrapped around the bracket 100 to form a receiving cavity 101 , and the receiving cavity 101 is used to receive the compressor 600 .

[0045] It is understandable that the sound insulation cotton 200 is generally made of a soft material. If the sound insulation cotton 200 is directly wrapped around the compressor 600, the sound insulation cotton 200 may be deformed, bent, etc., which will cause the compressor 600 to be not tightly sealed and leak more sound. The sound insulation cotton 200 is directly installed on the bracket 100, so that the bracket 100 provides support for the sound insulation cotton 200, which is conducive to forming a well-sealed receiving cavity 101, thereby avoiding sound leakage and improving the noise reduction effect. In one embodiment, the sound insulation cotton 200 is coated on the outside of the bracket 100, which can increase the volume of the receiving cavity 101, increase the material of the sound insulation cotton 200, and thus improve the noise processing ability. Of course, the sound insulation cotton 200 can also be coated on the inside of the bracket 100.

[0046] In an embodiment of the present invention, the sound insulation cotton 200 includes a top sound insulation cotton 210 and a side sound insulation cotton 220. The top sound insulation cotton 210 is located on the top of the bracket 100, and the side sound insulation cotton 220 is covered on the side of the bracket 100. In this way, compared with the whole sound insulation cotton 200, the separate sound insulation cotton 200 is avoided from deformation and bending, ensuring the sealing of the receiving cavity 101 and facilitating the installation of the sound insulation cotton 200.

[0047] In the embodiment of the present invention, the side sound insulation cotton 220 includes a plurality of side sound insulation cottons 221, and the plurality of side sound insulation cottons 221 are sequentially connected to the bracket 100. In this way, the installation convenience of the side sound insulation cotton 220 is further improved.

[0048] In an embodiment of the present invention, the noise reduction structure further includes a compressor cover (not shown), which includes a plurality of side panels (not shown), and a side panel is connected to the outer side of a side sound insulation cotton 221.

[0049] Specifically, the sound insulation cotton 200 is installed on the outside of the bracket 100, and the compressor cover is set on the outside of the sound insulation cotton 200. The compressor cover includes multiple side panels, and a side panel is installed on the outside of a side sound insulation cotton 221. In this way, the noise treatment effect is further improved.

[0050] More specifically, the sound insulation cotton 200 can be connected to the compressor cover by different methods such as glue, double-sided tape, M glue, rivet nuts, tightening belts, screws, etc. The sound insulation cotton 200 is made of soft, porous and strong sound-absorbing material. When the sound waves enter the pores, it causes the fibers to vibrate, and the sound energy is converted into heat energy through viscosity and friction, which is absorbed and dissipated. The sound insulation cotton 200 includes one or more of PP / PET two-component sound insulation cotton, glass fiber cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, and slag wool. The material of the compressor cover includes one or more of damping steel plate, hot-dip galvanized steel plate, aluminum plate, stainless steel plate, ABS plastic, PP plastic, HIPS plastic, and hard rubber, among which the metal compressor cover can be formed by sheet metal technology.

[0051] PP refers to polypropylene, and PET stands for polyethylene terephthalate. PP / PET two-component sound insulation cotton 200 is a composite material, typically made from a blend of PP and PET fibers. It combines the properties of PP and PET, offering excellent elasticity and durability for sound insulation. HIPS stands for high-impact polystyrene, a thermoplastic material made from elastomer-modified polystyrene.

[0052] In an embodiment of the present invention, the compressor cover further includes a top cover (not shown), which is connected to the outer side of the top sound insulation cotton 210. In this way, the compressor cover also adopts a split setting, and the split setting of the compressor cover and the sound insulation cotton 200 matches, thereby facilitating the connection between the sound insulation cotton 200 and the compressor cover.

[0053] In an embodiment of the present invention, the sound insulation cotton 200 is configured as a multi-layer structure. This multi-layer structure facilitates improved noise reduction. In one embodiment, the multi-layer structure includes a rubber layer and a sound-absorbing cotton layer, with the rubber layer positioned outside the sound-absorbing cotton layer. In another embodiment, the sound insulation cotton 200 is a combination of multiple types of sound-absorbing cotton. In yet another embodiment, the sound insulation cotton 200 is a hard, pure sound-absorbing cotton.

[0054] In the embodiments of the present invention, the bracket 100 is made of metal or plastic. Metal materials include, but are not limited to, one or more of iron, aluminum, copper, and stainless steel. The metal bracket 100 can be processed using sheet metal processing. Plastic materials include, but are not limited to, one or more of ABS and HIPS. The material of the bracket 100 is not limited herein.

[0055] In the embodiment of the present invention, the sound insulation cotton 200 is fixed to the bracket 100 by screws. Thus, the screw fixing is beneficial to the stability, reliability and convenience of the connection between the sound insulation cotton 200 and the bracket 100.

[0056] In an embodiment of the present invention, the lower ends of the bracket 100 and the sound insulation cover 500 both have an opening 102, and the noise reduction structure also includes a sound insulation base 300 arranged in the opening 102, and the sound insulation base 300 is used for installing the compressor 600; and / or, the bracket 100 and the sound insulation base 300 are used to be locked to the chassis 400 of the air conditioner by screws.

[0057] Thus, the provision of the soundproof base 300 helps reduce the transmission of vibrations from the compressor 600 to the outside. In one embodiment, the soundproof base 300 is configured as rubber. However, the present design is not limited thereto; in other embodiments, the soundproof base 300 may also be configured as silicone, for example. Generally, the chassis 400 of an air conditioner is often constructed of plastic. The provision of a plastic chassis 400 and the soundproof base 300 can prevent and reduce the downward transmission of noise. Furthermore, the soundproof base 300 also helps prevent the generation of vibration noise from the collision between the compressor cover and the chassis 400.

[0058] In one embodiment, one end of the bracket 100 is folded outward toward the sound insulation base 300 to form a flange, and a screw hole is provided on the flange. The sound insulation base 300 is also provided with a screw hole. The screws pass through the two screw holes in sequence to fix the two to the chassis 400 of the air conditioner, thereby simplifying the connection method of the bracket 100, the sound insulation base 300 and the chassis 400.

[0059] The present invention also provides a compressor assembly (not shown), which includes a compressor 600 and a noise reduction structure. The specific structure of the noise reduction structure is similar to the above-mentioned embodiments. Since the present compressor assembly adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be described in detail here. Among them, the compressor 600 includes a body (not shown) and a pipe (not shown) connected to the body. The compressor 600 is accommodated in the accommodation chamber 101. The noise reduction structure has an extension port (not shown), and the outlet end of the pipe extends from the extension port.

[0060] Specifically, the compressor 600's housing and piping are housed within the bracket 100. The soundproof cover 500 has an opening through which the piping's outlet protrudes. This completes the noise reduction structure, encasing the compressor 600's housing and piping. Aside from the opening for piping and wiring, the entire structure is solid. This highly sealed design minimizes sound leakage, preventing sound energy leakage and diffraction, significantly enhancing noise reduction effectiveness.

[0061] The present utility model also proposes an air conditioner, which includes a compressor assembly. The specific structure of the compressor assembly refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0062] In an embodiment of the present invention, the air conditioner includes an indoor air conditioner unit (not shown) and an outdoor air conditioner unit (not shown); wherein, the compressor assembly is arranged in the indoor air conditioner unit; and / or, the indoor air conditioner unit and the outdoor air conditioner unit are connected by a flexible refrigerant pipe (not shown), and the flexible refrigerant pipe is pre-filled with refrigerant.

[0063] The air conditioner of the present invention can be a split-type air conditioner for easy user installation. By placing the compressor 600 in the indoor unit, the weight of the outdoor unit can be reduced, thereby facilitating installation of the outdoor unit. Accordingly, by placing the compressor 600 in the indoor unit, a noise reduction structure is required to ensure comfortable operation and low noise interference.

[0064] The air conditioner uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant pipes or add refrigerant. This reduces installation complexity and facilitates user-friendly installation. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner.

[0065] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
