[0043] 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.

[0044] At present, the noise control measure is generally to simply wrap a layer of sound insulation cotton, but the noise reduction effect of this method is limited.

[0045] In view of this, the present invention proposes a noise reduction structure.

[0046] See also Figure 1 and Figure 2 In one embodiment of the present invention, the noise reduction structure includes a compressor cover (not shown), the compressor cover is provided with a receiving cavity 150 for receiving the compressor, and the compressor cover includes at least one sound insulation material layer (not shown).

[0047] As is understandable, the compressor 10 generates vibration and noise during operation. The compressor cover is provided on the compressor 10 to reduce the noise generated during operation. Thus, compared to the prior art method of using only a single layer of sound insulation to reduce the noise of the compressor 10, the technical solution of the present utility model incorporates a compressor cover comprising at least one layer of sound insulation material within the noise reduction structure, thereby providing a multi-layered absorption and sealing treatment for the noise generated by the compressor 10. This reduces the possibility of sound energy leakage, significantly improves the noise reduction effect of the compressor 10, and thereby enhances the user comfort of the air conditioner.

[0048] In an embodiment of the present invention, the compressor cover is configured as a soundproof foam cover. Because the soundproof foam cover has a certain structural strength, it can provide support for the sound insulation material layer. It also has a certain density, which can block noise and reduce the possibility of sound energy leakage.

[0049] In an embodiment of the present invention, the compressor cover includes at least one cover body 100 and at least one sound insulation material layer (not shown) provided on the inner side or the outer side of the cover body.

[0050] Specifically, the noise reduction structure includes at least one cover body 100 and at least one layer of sound insulation material. The sound insulation material layer can be located on the inside or outside of the cover body 100. In one embodiment, when the noise reduction structure includes one cover body 100 and one layer of sound insulation material, or more than one cover body 100 and more than one layer of sound insulation material, or one cover body 100 and more than one layer of sound insulation material, or more than one cover body 100 and one layer of sound insulation material, the outside of the compressor 10 is always provided with a sound insulation material layer. In other words, in the noise reduction structure, the sound insulation material layer, rather than the cover body 100, is closest to the compressor 10 to improve the noise reduction effect. In one embodiment, the sound insulation material layer can be fixed to the cover body 100 using various methods, such as glue, double-sided tape, 3M glue, rivet nuts, tightening tape, screws, etc.

[0051] It is understandable that the compressor 10 will generate vibration and noise during operation. The main function of the sound insulation material layer is to absorb noise, and the main function of the cover body 100 is to seal the noise. Placing the sound insulation material layer directly close to the compressor 10 can absorb noise more directly and quickly. In the present invention, the sound insulation material layer is configured as a sound insulation foam layer or a sound insulation cotton layer 200. It is understandable that the foam has a porous structure, which enables the sound insulation foam layer to absorb noise. The sound insulation cotton layer 200 is made of a soft, porous, and highly sound-absorbing material. When sound waves enter the pores, they cause the fibers to vibrate, and the sound energy is converted into heat energy through viscosity and friction, which is then absorbed and dissipated. The provision of the cover body 100 can reduce the outward propagation of the compressor 10 system noise and reflect the noise as much as possible within the cover body 100. The cover body 100 is made of a dense, thick material to increase the sound insulation and noise reduction treatment of medium and low frequencies, to block and seal the noise in the internal space so that it is repeatedly absorbed by the sound insulation material layer, isolating it from the surrounding air.

[0052] In the present invention, the entire noise reduction structure wraps the compressor 10 and the piping. Except for the connecting openings for the piping and wires to pass through, the rest are all solid structures. The high sealing feature can reduce the sound leakage area, avoid sound energy leakage and diffraction, and greatly improve the noise reduction effect.

[0053] In one embodiment, a layer of sound insulation material is disposed on the outside of the compressor 10 to absorb the noise generated by the compressor 10 during operation. At least one cover body 100, or at least one cover body 100 and a layer of sound insulation material, is further disposed on the outside of the sound insulation layer to seal or both seal and absorb the noise emitted by the compressor 10. Compared to prior art solutions that rely solely on a single layer of sound insulation cotton to reduce the noise of the compressor 10, the present invention employs at least one layer of sound insulation material and at least one layer of cover body 100 to achieve multi-layered absorption and sealing of the noise generated by the compressor 10, reducing the possibility of sound energy leakage, significantly improving the noise reduction effect of the compressor 10, and thereby enhancing the user comfort of the air conditioner.

[0054] In an embodiment of the present invention, the sound insulation cotton layer 200 is provided with two layers, and the cover body 100 is provided with two layers. One sound insulation cotton layer 200 is used to wrap the compressor 10, and its outer side is provided with a cover body 100, another sound insulation cotton layer 200 and another cover body 100 in sequence.

[0055] Specifically, the sound insulation cotton layer 200 is provided with two layers, and the cover body 100 is also provided with two layers. The noise reduction structure is sequentially provided from the inside to the outside: a layer of sound insulation cotton layer 200, a layer of cover body 100, another layer of sound insulation cotton layer 200, and another layer of cover body 100. In one embodiment, in the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 100 can be made of: non-woven fiber cotton, ABS plastic, glass fiber cotton, or stainless steel plate.

[0056] It should be noted that ABS (Acrylonitrile-Butadiene-Styrene) is a common thermoplastic, made from a copolymer of acrylonitrile, butadiene, and styrene. The inner side refers to the direction closer to the compressor 10, while the outer side refers to the direction away from the compressor 10.

[0057] In an embodiment of the present invention, the sound insulation cotton layer 200 is provided with two layers, and the cover body 100 is provided with one layer. One sound insulation cotton layer 200 is used to wrap the compressor 10; the cover body 100 and another sound insulation cotton layer 200 are provided on its outside in sequence; or, another sound insulation cotton layer 200 and the cover body 100 are provided on its outside in sequence.

[0058] Specifically, the sound insulation cotton layer 200 is provided on both sides, and the cover body 100 is provided with a single layer. In one embodiment, the noise reduction structure is provided, from the inside to the outside, in the order of a sound insulation cotton layer 200, a layer of the cover body 100, and another layer of sound insulation cotton layer 200. In one embodiment, in the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 100 can be made of needle-punched felt, sheet metal, or glass fiber cotton.

[0059] In another embodiment, the noise reduction structure is sequentially arranged from the inside out to include a sound insulation cotton layer 200, another sound insulation cotton layer 200, and a cover body 100. In one embodiment, in the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 100 can be selected from: non-woven fiber cotton, PP / PET two-component sound insulation cotton, or aluminum plate.

[0060] Among them, PP refers to polypropylene, PET refers to polyethylene terephthalate, and PP / PET two-component sound insulation cotton is a composite material, usually made of a mixture of PP and PET fibers. It combines the characteristics of PP and PET, has good elasticity and durability, and is used for sound absorption and sound insulation.

[0061] In an embodiment of the present invention, the sound insulation cotton layer 200 is provided with one layer, and the cover body 100 is provided with two layers. The sound insulation cotton layer 200 is used to wrap the compressor 10, and a cover body 100 and another cover body 100 are sequentially provided on its outer side.

[0062] Specifically, the sound insulation layer 200 is provided in one layer, and the cover body 100 is provided in two layers. The noise reduction structure is provided, from the inside to the outside, in the order of one sound insulation layer 200, one cover body 100, and another cover body 100. In one embodiment, in the direction away from the compressor 10, the sound insulation layer 200 and the cover body 100 can be made of: PP / PET two-component sound insulation cotton, rubber, or damping steel plate.

[0063] In an embodiment of the present invention, the sound insulation cotton layer 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. Specifically, the present invention adopts high-performance sound insulation cotton material, and the porous structure of the sound insulation cotton layer 200 can convert sound energy into heat energy through viscosity and friction, thereby being absorbed and dissipated. The material of the sound insulation cotton layer 200 can be selected according to the number of layers of the sound insulation cotton layer 200 and the cover body 100 in the noise reduction structure, and / or the power of the compressor 10. The specific material of the sound insulation cotton layer 200 is not limited here.

[0064] In the embodiments of the present invention, the cover body 100 is configured with a single layer or multiple layers. When the cover body 100 is configured with multiple layers, at least one layer of the cover body 100 is made of metal and at least one layer of the cover body 100 is made of a non-metallic material. Alternatively, all multiple layers of the cover body 100 are made of metal, with at least two layers of the cover body 100 having different metal materials. Alternatively, all multiple layers of the cover body 100 are made of non-metallic materials, with at least two layers of the cover body 100 having different non-metallic materials. Because different materials have different sound reflection capabilities, at least two materials are used in the multi-layer cover body 100 to reflect sounds of different frequency bands, thereby improving the reflection effect and enhancing noise handling capabilities. When the cover body 100 is configured with a single layer, the single layer of the cover body 100 is made exclusively of metal or non-metallic material.

[0065] More specifically, metal materials include, but are not limited to, one or more of damping steel plates, vibration-damping composite steel plates, hot-dip galvanized steel plates, aluminum plates, and stainless steel plates. The metal cover body 100 can be processed using sheet metal processing. Non-metallic materials include, but are not limited to, one or more of ABS plastic, PP plastic, HIPS plastic, natural rubber, synthetic rubber, and PVC. The material of the cover body 100 can be selected based on the number of layers of the sound insulation cotton layer 200 and the cover body 100 in the noise reduction structure, and / or the power of the compressor 10. The specific material of the cover body 100 is not limited here.

[0066] In an embodiment of the present invention, the cover body 100 includes a first side panel 110, a second side panel 120 detachably connected to the first side panel 110, and a top cover 130 detachably connected to the first side panel 110 and the second side panel 120. The first side panel 110, the second side panel 120, and the top cover 130 enclose a receiving cavity 150. In this way, the difficulty of producing the cover body 100 is reduced by dividing the cover body 100 into several components. However, the present design is not limited to this. In other embodiments, the cover body 100 is an integrally molded component. In another embodiment, the cover body 100 may further include an upper end cover and a side panel, wherein the side panel is cylindrical and has an opening at both ends. The upper end cover is detachably connected to an open end of the side panel. In this way, the separate setting of the cover body 100 can also be achieved, thereby improving the efficiency of disassembly and assembly of the cover body 100.

[0067] In one embodiment, the first side panel 110 and the second side panel 120 are connected via a snap-fit ​​structure. This snap-fit ​​connection allows the first and second side panels 110, 120 to be quickly joined together, making installation and removal of the housing body 100 easier. It also facilitates assembly of the housing body 100's internal structure, fully utilizing the space available. Efficient assembly of the housing body 100 can also meet the high production speeds of air conditioner production lines. However, this design is not limited to this. In other embodiments, the first and second side panels 110, 120 are screwed together to enhance the stability of their connection.

[0068] In one embodiment, one of the first side panel 110 and the second side panel 120 is provided with a hook 121, and the other is provided with a slot 111. The hook 121 engages with the slot 111 to connect the first side panel 110 and the second side panel 120. In one embodiment, multiple slots 111 are spaced apart on the first side panel 110, and multiple hooks 121 are spaced apart on the second side panel 120. The number and position of the slots 111 and the hooks 121 correspond. This improves the stability and reliability of the connection between the first and second side panels 110, 120. Of course, it is also possible to provide both the slots 111 and the hooks 121 on the first side panel 110, and correspondingly provide the hooks 121 and slots 111 on the second side panel 120. As long as the hooks 121 and slots 111 engage in a one-to-one correspondence, it will suffice.

[0069] However, the present design is not limited thereto. In other embodiments, one of the first side panel 110 and the second side panel 120 may be provided with a snap-fit ​​pin, and the other one may be provided with a snap-fit ​​hole. In this way, the snap-fitting of the first side panel 110 and the second side panel 120 can also be achieved.

[0070] In one embodiment, the card slot 111 includes a connected insertion slot (not shown) and a connecting slot (not shown), the diameter of the connecting slot is smaller than the insertion slot, and the hook 121 is inserted into the connecting slot. Specifically, the card slot 111 is a special-shaped slot, which includes a connected insertion slot and a connecting slot. When the hook 121 is connected to the card slot 111, the hook 121 first extends into the insertion slot portion of the card slot 111, and then slides into the connecting slot portion, thereby inserting the hook 121 into the connecting slot. The setting of the insertion slot having a diameter larger than the connecting slot allows the hook 121 to easily enter the insertion slot, eliminating the need to accurately align the hook 121 and the card slot 111 in advance, thereby improving the simplicity of connecting the hook 121 and the card slot 111.

[0071] In one embodiment, the diameter of the engaging slot gradually decreases in the direction away from the insertion slot, so that the engagement between the hook 121 and the engaging slot is more secure, preventing the hook 121 from falling out of the engaging slot.

[0072] In one embodiment, the hook 121 is provided on the second side panel 120, and the hook 121 includes an abutting portion (not shown) and an anti-slip portion (not shown). The hook 121 is snapped into the snap-in groove so that the abutting portion contacts the bottom wall of the snap-in groove, and the anti-slip portion is located on the side of the first side panel 110 facing away from the second side panel 120.

[0073] As will be appreciated, the abutment and the anti-slip portion are arranged at an angle. In one embodiment, the abutment and anti-slip portion are arranged in an "L" shape. When the hook 121 is inserted into the slot 111, the abutment contacts the bottom wall of the slot, while the anti-slip portion contacts the side of the first side panel 110 facing away from the second side panel 120. The abutment ensures that the hook 121 and the slot 111 are securely connected, while the anti-slip portion prevents the hook 121 from being dislodged from the slot 111, thereby preventing the connection between the first and second side panels 110, 120 from failing.

[0074] In one embodiment, hook 121 is provided with a rib (not shown) that abuts against the sidewalls of the engaging slot. Specifically, the rib can be convex or concave on hook 121. When hook 121 is engaged with slot 111, the rib abuts against the sidewalls of the engaging slot. The provision of the rib reduces the precision of the fit between hook 121 and slot 111, and reduces the difficulty of manufacturing the hook 121 and slot 111.

[0075] In one embodiment, the first side panel 110 and the second side panel 120 both include a panel body 171, and the panel body 171 is connected to an extension section 172 at one end close to the top cover 130. The extension section 172 is recessed relative to the panel body 171, and a step portion 173 is formed between the two. The extension section 172 extends into the top cover 130, and the cover edge of the top cover 130 abuts against the step portion 173.

[0076] As will be appreciated, when the first and second side panels 110, 120 are combined, the circumference of the extended section 172 along the circumference of the cover body 100 is smaller than the circumference of the panel body 171. Consequently, when the top cover 130 is connected to the first and second side panels 110, 120, the top cover 130 extends beyond the extended section 172, allowing the extended section 172 to extend into the top cover 130, with the cover edge of the top cover 130 abutting the step 173. In one embodiment, the outer surface of the sidewall of the top cover 130 is flush with the outer surface of the step 173, that is, the outer surface of the sidewall of the top cover 130 is flush with the outer surface of the panel body 171. This improves the aesthetic appearance of the cover body 100 and the aesthetic appearance of the noise reduction structure.

[0077] In one embodiment, a plurality of extending sections 172 are provided, and the plurality of extending sections 172 are spaced apart along the circumference of the cover body 100. Thus, a buffer groove 175 is formed between two adjacent extending sections 172. The provision of the buffer groove 175 allows the extending sections 172 to have a certain degree of deformation force, thereby facilitating the installation of the top cover 130 over the first and second side panels 110, 120, and reducing the precision requirements for the fit between the top cover 130, the first and second side panels 110, 120, thereby improving the ease of assembly and disassembly of the top cover 130, the first and second side panels 110, 120.

[0078] In one embodiment, the extending section 172 is provided with a guide structure at the end away from the panel body 171. The guide structure is configured as an inwardly inclined guide flange 174. The provision of the guide flange 174 provides precise guidance for the connection between the top cover 130 and the first and second side panels 110, 120, thereby improving the connection speed of the top cover 130, the first and second side panels 110, 120, and the assembly efficiency of the cover body 100.

[0079] In one embodiment, the first side panel 110 and the top cover 130 are connected by bolts, and / or the second side panel 120 and the top cover 130 are connected by bolts; and / or, in the circumferential direction of the cover body 100, the length of one of the first side panel 110 and the second side panel 120 is greater than the length of the other.

[0080] Specifically, after the first and second side panels 110 and 120 are fastened together, the top cover 130 is placed over the first and second side panels 110 and 120. To enhance the connection stability between the first and second side panels 110 and 120, connection holes are provided in the first and second side panels 110 and 120, respectively. Bolts are inserted through the holes to connect the first and second side panels 110 and 120. To enhance the connection stability between the second and second side panels 120 and 120, connection holes are provided in the second and second side panels 120 and 120, respectively. Bolts are inserted through the holes to connect the second and second side panels 120 and 120. Furthermore, the shape and size of the first and second side panels 110 and 120 can be adjusted according to the configuration of the compressor 10, and their sizes can be the same or different. In the embodiment shown in the drawings of the present invention, the length of the first and second side panels 110 is greater than the length of the second side panels 120 in the circumferential direction of the housing body 100. At this time, the first side panel 110 can be connected to the top cover 130 by two screws, and the second side panel 120 can be connected to the top cover 130 by one screw. After the screws are locked, the entire noise reduction structure components will not move relative to each other, and the connection strength is high.

[0081] In this way, the first side panel 110, the second side panel 120, and the top cover 130 are detachably connected through snap-fitting, while the screw fastening improves the stability and reliability of the connection.
