[0045] The compressor plays a crucial role in the air conditioning refrigerant circuit, compressing and driving the refrigerant, and it generates noise during operation. Currently, to reduce compressor noise, a compressor cover is typically installed on the outside of the compressor. Most commonly used compressor covers are one-piece structures, which can be cumbersome to disassemble and reassemble in some situations, such as during compressor maintenance.

[0046] This application proposes a noise reduction structure.

[0047] Please refer to Figures 1 to 4. In one embodiment of this application, the noise reduction structure includes a compressor cover 100. The compressor cover 100 is provided with a receiving cavity 150 for accommodating the compressor. The compressor cover 100 includes a plurality of splicing parts, which surround the receiving cavity 150.

[0048] Understandably, compressors generate vibration and noise during operation. The compressor cover 100, located outside the compressor, reduces the outward propagation of compressor system noise, reflecting it as much as possible within the cover. The compressor cover 100 is constructed of dense, thick materials to enhance low- and mid-frequency sound insulation and noise reduction, blocking and enclosing noise within the internal space where it is repeatedly absorbed by sound-absorbing cotton, thus isolating it from the surrounding air. More specifically, the compressor cover 100 is made of one or more of the following materials, including but not limited to damping steel plates, vibration-damping composite steel plates, hot-dip galvanized steel plates, aluminum plates, and stainless steel plates.

[0049] In one embodiment, sound-absorbing cotton is also provided inside the compressor cover 100 to wrap the compressor. The sound-absorbing cotton can be fixed to the compressor cover 100 by various methods such as glue, double-sided tape, 3M adhesive, rivet nuts, fastening straps, and screws. The sound-absorbing cotton 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 adhesion and friction, thereby being absorbed and dissipated. More specifically, the sound-absorbing cotton includes, but is not limited to, one or more of the following: PP / PET two-component sound-absorbing cotton, glass fiber cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, and slag wool.

[0050] PP refers to polypropylene, and PET refers to polyethylene terephthalate. PP / PET bicomponent sound insulation cotton is a composite material, usually made of a mixture of PP and PET fibers. It combines the properties of PP and PET, has good elasticity and durability, and is used for sound absorption and sound insulation.

[0051] In one embodiment, the noise reduction structure may include at least one compressor cover 100 and at least one layer of sound insulation cotton, thereby improving the noise reduction capability. In one embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has two layers; one layer of sound insulation cotton is used to wrap the compressor, and a compressor cover 100, another layer of sound insulation cotton, and another compressor cover 100 are sequentially arranged on its outer side. In another embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has one layer; one layer of sound insulation cotton is used to wrap the compressor, and a compressor cover 100 and another layer of sound insulation cotton are sequentially arranged on its outer side; or, another layer of sound insulation cotton and a compressor cover 100 are sequentially arranged on its outer side. In yet another embodiment, the sound insulation cotton has one layer, and the compressor cover 100 has two layers; the sound insulation cotton is used to wrap the compressor, and a compressor cover 100 and another compressor cover 100 are sequentially arranged on its outer side. No restrictions are placed on the number of layers or the arrangement order of the compressor cover 100 and the sound insulation cotton.

[0052] In this application, the entire noise reduction structure encloses the compressor and piping. Except for the opening for the piping and wires to pass through, the rest is a solid structure. The high sealing feature can reduce the sound leakage area, avoid sound energy leakage and diffraction, and greatly improve the noise reduction effect.

[0053] The technical solution of this application provides a compressor cover 100 with a receiving cavity 150 in a noise reduction structure. The compressor cover 100 includes multiple splicing parts that surround the receiving cavity 150 for housing the compressor. Thus, compared to the prior art where the compressor cover 100 is a single unit, this application provides a split structure for the compressor cover 100. On the one hand, the split compressor cover 100 improves the assembly and disassembly efficiency of the noise reduction structure; on the other hand, some splicing parts can be removed at any time to observe the operation of the components inside the compressor cover 100, facilitating inspection and maintenance; furthermore, the split compressor cover 100 allows for the installation of components such as the compressor within it through splicing, thereby promoting the miniaturization, lightweighting, and cost reduction of the compressor cover 100.

[0054] Referring to Figure 1, in an embodiment of this application, the compressor cover 100 includes a first side panel 110, a second side panel 120, and a top cover 130. The first side panel 110 and the second side panel 120 are detachably connected, and the top cover 130 is detachably connected to the first side panel 110 and the second side panel 120. Thus, the compressor cover 100 is configured as three separate splicing parts. The first side panel 110, the second side panel 120, and the top cover 130 enclose a receiving cavity 150, wherein each pair of splicing parts is detachably connected, thereby improving the assembly and disassembly efficiency of the compressor cover 100 and facilitating the inspection and maintenance of the compressor.

[0055] However, this design is not limited to this. In other embodiments, the compressor cover 100 may also include two splicing parts: an upper cover and a side panel. The side panel is cylindrical with openings at both ends, and the upper cover is detachably connected to one opening of the side panel. In this way, the compressor cover 100 can also be set up separately, which improves the assembly and disassembly efficiency of the compressor cover 100.

[0056] In the embodiments of this application, the first side panel 110 and the second side panel 120 are connected by a snap-fit ​​structure. This snap-fit ​​allows for quick assembly of the first side panel 110 and the second side panel 120, making the installation and disassembly of the compressor cover 100 easier. It also facilitates the assembly of the internal structure of the compressor cover 100, making full use of space. The efficient assembly of the compressor cover 100 also meets the high line-speed requirements of air conditioner production lines. However, this design is not limited to this. In other embodiments, the first side panel 110 and the second side panel 120 can also be detachably connected using multiple bolts.

[0057] Referring to Figure 1, in an embodiment of this application, 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, the first side panel 110 is provided with a plurality of slots 111 spaced apart, and the second side panel 120 is provided with a plurality of hooks 121 spaced apart, with the number and position of the slots 111 and hooks 121 corresponding. This improves the connection stability and reliability of the first side panel 110 and the second side panel 120. Of course, it is also possible to provide both slots 111 and hooks 121 on the first side panel 110, and correspondingly provide hooks 121 and slots 111 on the second side panel 120, as long as the hooks 121 and slots 111 engage one-to-one.

[0058] However, this design is not limited to this. 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 may be provided with a snap-fit ​​hole, so that the snap-fit ​​of the first side panel 110 and the second side panel 120 can also be achieved.

[0059] Referring to Figures 1 and 2, in the embodiments of this application, the slot 111 includes a communicating insertion slot 112 and a snap-fit ​​slot 113. The diameter of the snap-fit ​​slot 113 is smaller than that of the insertion slot 112, and the hook 121 snaps into the snap-fit ​​slot 113. Specifically, the slot 111 is an irregularly shaped slot, which includes a communicating insertion slot 112 and a snap-fit ​​slot 113. When the hook 121 snaps into the slot 111, the hook 121 first extends into the insertion slot 112 portion of the slot 111, and then slides into the snap-fit ​​slot 113 portion, thereby snapping the hook 121 into the snap-fit ​​slot 113. The diameter of the insertion groove 112 is larger than the diameter of the snap-fit ​​groove 113, and the diameter of the insertion groove 112 is larger than the diameter of the hook 121, so that the hook 121 can easily enter the insertion groove 112 without the need to precisely align the hook 121 and the snap-fit ​​groove 111 in advance, which improves the ease of snapping the hook 121 and the snap-fit ​​groove 111.

[0060] Referring to Figure 2, in the embodiments of this application, the diameter of the snap-fit ​​groove 113 gradually decreases in the direction away from the insertion groove 112. This makes the snap-fit ​​between the hook 121 and the snap-fit ​​groove 113 more secure, preventing the hook 121 from coming out of the snap-fit ​​groove 113.

[0061] Please refer to Figures 1 and 3. In the embodiments of this application, the hook 121 is provided on the second side panel 120. The hook 121 includes an abutment portion 122 and an anti-detachment portion 123. The hook 121 is engaged in the snap-fit ​​groove 113 so that the abutment portion 122 contacts the bottom wall of the snap-fit ​​groove 113. The anti-detachment portion 123 is located on the side of the first side panel 110 away from the second side panel 120.

[0062] Understandably, the abutment portion 122 and the anti-detachment portion 123 are arranged at an angle; in one embodiment, they are arranged in an "L" shape. When the hook 121 is engaged in the slot 111, the abutment portion 122 contacts the bottom wall of the slot 113, and the anti-detachment portion 123 contacts the side of the first side panel 110 opposite to the second side panel 120. The abutment portion 122 ensures that the hook 121 and the slot 111 are engaged, and the anti-detachment portion 123 prevents the hook 121 from coming out of the slot 111, thus preventing the connection between the first side panel 110 and the second side panel 120 from failing.

[0063] Please refer to Figures 1 and 3. In the embodiments of this application, the hook 121 is provided with a protruding rib 124, which abuts against the sidewall of the locking groove 113. Specifically, the protruding rib 124 on the hook 121 can be either convex or concave. When the hook 121 is engaged in the locking groove 111, the protruding rib 124 abuts against the sidewall of the locking groove 113. The provision of the protruding rib 124 reduces the fitting accuracy between the hook 121 and the locking groove 111, and reduces the processing difficulty of the hook 121 and the locking groove 111.

[0064] Please refer to Figures 1 and 4. In the embodiments of this application, both the first side panel 110 and the second side panel 120 include a panel body 171. The panel body 171 has an extension section 172 connected to one end near 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.

[0065] Understandably, after the first side panel 110 and the second side panel 120 are joined together, the perimeter of the extension section 172 along the circumference of the compressor cover 100 is smaller than the perimeter of the plate body 171. Thus, when the top cover 130 is connected to the first side panel 110 and the second side panel 120, the top cover 130 covers the extension section 172, allowing the extension section 172 to extend into the top cover 130, and the edge of the top cover 130 abuts against the step portion 173. In one embodiment, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the step portion 173, that is, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the plate body 171. This is beneficial to the aesthetic appearance of the compressor cover 100 and the noise reduction structure.

[0066] Please refer to Figures 1 and 4. In the embodiments of this application, multiple extension sections 172 are provided, and the multiple extension sections 172 are spaced apart circumferentially along the compressor cover 100. Thus, a buffer groove 175 is formed between two adjacent extension sections 172. The provision of the buffer groove 175 allows the extension section 172 to have a certain deformation force, thereby facilitating the placement of the top cover 130 on the first side panel 110 and the second side panel 120. This reduces the fitting accuracy requirements between the top cover 130, the first side panel 110 and the second side panel 120, and improves the ease of disassembly and assembly of the top cover 130, the first side panel 110 and the second side panel 120.

[0067] Referring to Figures 1 and 4, in the embodiments of this application, the extension section 172 has a guide structure at the end away from the plate body 171. The guide structure is configured as an inwardly inclined guide flange 174. The guide flange 174 provides precise guidance for the connection between the top cover 130 and the first side panel 110 and the second side panel 120, improving the connection speed between the top cover 130 and the first side panel 110 and the second side panel 120, and improving the assembly efficiency of the compressor cover 100.

[0068] Please refer to Figure 1. In the embodiments of this application, 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 compressor cover 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.

[0069] Specifically, after the first side panel 110 and the second side panel 120 are engaged, the top cover 130 is placed over the first side panel 110 and the second side panel 120. To improve the connection stability between the first side panel 110 and the top cover 130, connection holes are respectively made on the first side panel 110 and the top cover 130, and bolts pass through the two connection holes to connect the first side panel 110 and the top cover 130. To improve the connection stability between the second side panel 120 and the top cover 130, connection holes are respectively made on the second side panel 120 and the top cover 130, and bolts pass through the two connection holes to connect the second side panel 120 and the top cover 130. In addition, the shape and size of the first side panel 110 and the second side panel 120 can be adjusted according to the configuration of the compressor, and their sizes can be the same or different. In the scheme shown in the figures of this application, the length of the first side panel 110 is greater than the length of the second side panel 120 in the circumferential direction of the compressor cover 100. At this point, the first side panel 110 can be connected to the top cover 130 with two screws, and the second side panel 120 can be connected to the top cover 130 with one screw. After the screws are locked, the components of the entire noise reduction structure will not be able to move relative to each other, resulting in high connection strength.

[0070] Thus, the first side panel 110, the second side panel 120, and the top cover 130 are detachably connected by snap-fit, while the connection stability and reliability are improved by screw fastening. In one embodiment, the three components can be fastened with only three screws, reducing the number of screws used, saving screw fastening time, and improving assembly efficiency.

[0071] Referring to Figure 1, in one embodiment, the lower end of the compressor housing 100 has an opening 140. The noise reduction structure also includes a base disposed at the opening 140. The base is made of an elastic element and is used for mounting the compressor. Thus, the elastic element helps reduce the transmission of compressor vibration to the outside. In one embodiment, the elastic element is made of rubber. However, this design is not limited to this; in other embodiments, the elastic element may also be made of silicone or the like.

[0072] In one embodiment, a chassis for the indoor air conditioning unit is also provided below the base, and the chassis is used for mounting the compressor cover 100. Generally, the chassis is made of plastic. The combination of the plastic chassis and the elastic base can prevent and reduce the downward transmission of noise, and the elastic element helps to prevent the generation of collision vibration noise between the compressor cover 100 and the chassis.

[0073] In the embodiments of this application, the sound insulation cotton includes a first-side sound insulation cotton, a second-side sound insulation cotton, and a top sound insulation cotton, which are separately arranged. The first-side sound insulation cotton is disposed on the inner side of the first side panel 110, the second-side sound insulation cotton is disposed on the inner side of the second side panel 120, and the top sound insulation cotton is disposed on the inner side of the top cover 130. This facilitates the installation of the compressor cover 100 and the sound insulation cotton.

[0074] In the embodiments of this application, please refer to FIG5. The compressor cover 100 is provided with a positioning rib 180. The positioning rib 180 is used for the installation and positioning of the wire harness fixing component. The wire harness fixing component is used to fix the wire harness of the air conditioner.

[0075] Specifically, a wire harness fixing member 190 is connected to the compressor cover 100, and the wire harness fixing member 190 is used to fix the wire harness of the air conditioner. In one embodiment, the wire harness fixing member 190 is welded to the compressor cover 100. The wire harness fixing member 190 can facilitate the straightening and fixing of the wire harness in the air conditioner, facilitate the management and maintenance of the wire harness, and also contribute to the aesthetics of the wiring.

[0076] To facilitate the installation of the wire harness fastener 190, a positioning rib 180 is provided on the compressor cover 100. When installing the wire harness fastener 190, the wire harness fastener 190 abuts against the positioning rib 180, thereby determining the installation position of the wire harness fastener 190 and improving the installation efficiency and accuracy of the installation position. In one embodiment, the positioning rib 180 has an "L" shape to position the wire harness fastener 190 in two directions, thereby improving the positioning accuracy of the wire harness fastener 190.

[0077] In one embodiment, the wire harness fixing member 190 is configured as a flexible metal strip. The flexible metal strip can be deformed at will to clamp the wire harness, facilitating wire harness fixation. However, this design is not limited to this; in other embodiments, the wire harness fixing member 190 can also be a strap, cable tie, etc. In one embodiment, the flexible metal strip is wrapped with an adhesive layer. The adhesive layer improves the user experience of the wire harness fixing member 190, prevents accidental injury to the user from the flexible metal strip, and also prevents wear and tear on the wire harness from the flexible metal strip. In one embodiment, the adhesive layer is configured as a silicone layer, a rubber layer, etc.

[0078] Portable air conditioners are portable devices that can be moved around freely and placed in different rooms, making air conditioning more convenient. Currently, both portable and split-type portable air conditioners place the compressor in the indoor unit. However, the compressor generates considerable noise when operating, which can affect the comfort of using the air conditioner.

[0079] Currently, noise control measures generally involve simply wrapping the area with a layer of sound-absorbing cotton, but this method has limited noise reduction effect.

[0080] In view of this, this application proposes a noise reduction structure.

[0081] Please refer to Figures 6 and 7. In one embodiment of this application, the noise reduction structure includes a compressor cover, which has a receiving cavity 150 for housing the compressor, and the compressor cover includes at least one layer of sound-insulating material.

[0082] It is understandable that the compressor 10 will generate vibration and noise during operation. A compressor cover is installed on the compressor 10 to reduce the noise generated during operation. Therefore, compared to the prior art which uses only a single layer of sound-absorbing cotton to reduce noise in the compressor 10, the technical solution of this application, by incorporating a compressor cover with at least one layer of sound-absorbing material into the noise reduction structure, provides 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 thus improving the user comfort of the air conditioner.

[0083] In the embodiments of this application, the compressor cover is configured as a sound-insulating foam cover. Because the sound-insulating foam cover has a certain structural strength, it can provide support for the sound-insulating material layer. At the same time, the sound-insulating foam cover also has a certain density, which can block noise and reduce the possibility of sound energy leakage.

[0084] In embodiments of this application, the compressor cover includes at least one cover body 102 and at least one sound-insulating material layer disposed on the inner or outer side of the cover body.

[0085] Specifically, the noise reduction structure includes at least one cover body 102 and at least one sound insulation material layer. The sound insulation material layer can be disposed on the inner side or the outer side of the cover body 102. In one embodiment, when the noise reduction structure includes one cover body 102 and one sound insulation material layer, or more than one cover body 102 and more than one sound insulation material layer, or one cover body 102 and more than one sound insulation material layer, or more than one cover body 102 and one sound insulation material layer, the outer side of the compressor 10 is always provided as the sound insulation material layer. In other words, in the noise reduction structure, the part closest to the compressor 10 is the sound insulation material layer, not the cover body 102, to improve the noise reduction effect. In one embodiment, the sound insulation material layer can be fixed to the cover body 102 by different methods such as glue, double-sided tape, 3M adhesive, rivet nuts, fastening straps, and screws.

[0086] Understandably, the compressor 10 generates vibration and noise during operation. The main function of the sound insulation material layer is to absorb noise, and the main function of the enclosure 102 is to seal off noise. Placing the sound insulation material layer directly close to the compressor 10 allows for more direct and rapid noise absorption. In this application, the sound insulation material layer is configured as a sound insulation foam layer or a sound insulation cotton layer 200. It is understood that foam has a porous structure, enabling the sound insulation foam layer to absorb noise. The sound insulation cotton layer 200 uses a soft, porous, and highly sound-absorbing material. When sound waves enter the pores, they cause fiber vibration, converting sound energy into heat energy through adhesion and friction, thus being absorbed and dissipated. The enclosure 102 reduces the outward propagation of noise from the compressor 10 system, reflecting noise as much as possible within the enclosure 102. The enclosure 102 is constructed of a dense and thick material to enhance mid-to-low frequency sound insulation and noise reduction, blocking and sealing noise within the internal space for repeated absorption by the sound insulation material layer, thus isolating it from the surrounding air.

[0087] In this application, the entire noise reduction structure encloses the compressor 10 and piping. Except for the opening for the piping and wires to pass through, the rest is a solid structure. The high sealing feature can reduce the sound leakage area, avoid sound energy leakage and diffraction, and greatly improve the noise reduction effect.

[0088] A sound-insulating material layer is provided on the outside of the compressor 10 to absorb the noise generated when the compressor 10 is working. At least one cover body 102 or at least one cover body 102 and a sound-insulating material layer are then provided on the outside of the sound-insulating material layer, thereby sealing or sealing and re-absorbing the noise emitted by the compressor 10. Compared with the prior art, which relies on only a single layer of sound-insulating cotton to reduce the noise of the compressor 10, this application provides at least one sound-insulating material layer and at least one cover body 102, thereby providing multi-layer absorption and sealing treatment for 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 thus improving the user comfort of the air conditioner.

[0089] In the embodiments of this application, the sound insulation cotton layer 200 has two layers, and the cover body 102 has two layers. One sound insulation cotton layer 200 is used to wrap the compressor 10, and a cover body 102, another sound insulation cotton layer 200 and another cover body 102 are arranged on its outer side in sequence.

[0090] Specifically, the sound insulation cotton layer 200 has two layers, and the cover body 102 also has two layers. The noise reduction structure is arranged from the inside out as one layer of sound insulation cotton layer 200, one layer of cover body 102, another layer of sound insulation cotton layer 200, and another layer of cover body 102. In the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 102 can be selected from: non-woven fiber cotton, ABS plastic, glass fiber cotton, and stainless steel plate.

[0091] It should be noted that ABS plastic (acrylonitrile-butadiene-styrene copolymer) is a common thermoplastic, copolymerized from three monomers: acrylonitrile, butadiene, and styrene. The inner side refers to the direction closer to compressor 10, and the outer side refers to the direction farther from compressor 10.

[0092] In the embodiments of this application, the sound insulation cotton layer 200 is provided in two layers, and the cover body 102 is provided in one layer. One sound insulation cotton layer 200 is used to wrap the compressor 10; the cover body 102 and another sound insulation cotton layer 200 are provided in sequence on its outer side; or, the other sound insulation cotton layer 200 and the cover body 102 are provided in sequence on its outer side.

[0093] Specifically, the sound insulation cotton layer 200 has two sides, and the cover body 102 has one layer. In one embodiment, the noise reduction structure is configured from the inside out as a layer of sound insulation cotton layer 200, a layer of cover body 102, and another layer of sound insulation cotton layer 200. In the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 102 can be selected as: needle-punched felt cotton, sheet metal, or fiberglass cotton.

[0094] In another embodiment, the noise reduction structure is configured from the inside out as a sound insulation cotton layer 200, another sound insulation cotton layer 200, and a cover body 102. In the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 102 can be selected as: non-woven fiber cotton, PP / PET two-component sound insulation cotton, or aluminum plate.

[0095] PP refers to polypropylene, and PET refers to polyethylene terephthalate. PP / PET bicomponent sound insulation cotton is a composite material, usually made of a mixture of PP and PET fibers. It combines the properties of PP and PET, has good elasticity and durability, and is used for sound absorption and sound insulation.

[0096] In the embodiments of this application, the sound insulation cotton layer 200 is provided with one layer, and the cover body 102 is provided with two layers. The sound insulation cotton layer 200 is used to wrap the compressor 10, and a cover body 102 and another cover body 102 are provided on its outer side in sequence.

[0097] Specifically, the sound insulation cotton layer 200 is provided in one layer, and the cover body 102 is provided in two layers. The noise reduction structure is arranged from the inside out as one layer of sound insulation cotton layer 200, one layer of cover body 102, and another layer of cover body 102. In the direction away from the compressor 10, the sound insulation cotton layer 200 and the cover body 102 can be selected as: PP / PET two-component sound insulation cotton, rubber, or damping steel plate.

[0098] In the embodiments of this application, the sound insulation cotton layer 200 includes one or more of the following: PP / PET bicomponent sound insulation cotton, glass fiber cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, and slag wool. Specifically, this application uses high-performance sound insulation cotton materials. The porous structure of the sound insulation cotton layer 200 can convert sound energy into heat energy through adhesion 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 102 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.

[0099] In the embodiments of this application, the cover body 102 is provided with a single layer or multiple layers. When the cover body 102 is provided with multiple layers, at least one layer of the cover body 102 is made of metal, and at least one layer of the cover body 102 is made of non-metallic material; or, all multiple layers of the cover body 102 are made of metal, and at least two layers of the cover body 102 are made of different metal materials; or, all multiple layers of the cover body 102 are made of non-metallic material, and at least two layers of the cover body 102 are made of different non-metallic materials. Because different materials have different sound reflection capabilities, at least two materials are used in the multi-layer cover body 102 to reflect sound in different frequency bands, thereby improving the reflection effect and noise processing capability. When the cover body 102 is provided with a single layer, the single layer of the cover body 102 is made of only metal or non-metallic material.

[0100] More specifically, the metal materials include, but are not limited to, one or more of the following: damping steel plate, vibration-damping composite steel plate, hot-dip galvanized steel plate, aluminum plate, and stainless steel plate. The metal cover body 102 can be processed using sheet metal techniques. Non-metallic materials include, but are not limited to, one or more of the following: ABS plastic, PP plastic, HIPS plastic, natural rubber, synthetic rubber, and PVC. The material of the cover body 102 can be selected based on the number of sound insulation cotton layers 200 in the noise reduction structure and the number of layers in the cover body 102, and / or the power of the compressor 10. No specific limitations are imposed on the specific material of the cover body 102 here.

[0101] In an embodiment of this application, the cover body 102 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. Thus, by dividing the cover body 102 into several components, the difficulty of manufacturing the cover body 102 is reduced. However, this design is not limited to this; in other embodiments, the cover body 102 is a one-piece molded component. In another embodiment, the cover body 102 may further include an upper end cover and side panels, wherein the side panels are cylindrical with openings at both ends, and the upper end cover is detachably connected to one opening end of the side panel. This also allows for a split design of the cover body 102, improving the efficiency of assembling and disassembling the cover body 102.

[0102] In one embodiment, the first side panel 110 and the second side panel 120 are connected by a snap-fit ​​structure. This snap-fit ​​allows for quick assembly of the first side panel 110 and the second side panel 120, making the installation and disassembly of the cover body 102 easier. It also facilitates the assembly of the internal structure of the cover body 102, making full use of space. The efficient assembly of the cover body 102 also meets the high-speed production requirements of air conditioner production lines. However, this design is not limited to this. In other embodiments, the first side panel 110 and the second side panel 120 are screwed together to improve the connection stability of the first side panel 110 and the second side panel 120.

[0103] 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, the first side panel 110 is provided with a plurality of slots 111 spaced apart, and the second side panel 120 is provided with a plurality of hooks 121 spaced apart. The number and position of the slots 111 and the hooks 121 correspond. This improves the connection stability and reliability of the first side panel 110 and the second side panel 120. Of course, it is also possible to provide both slots 111 and hooks 121 on the first side panel 110, and correspondingly provide hooks 121 and slots 111 on the second side panel 120, as long as the hooks 121 and slots 111 engage one-to-one.

[0104] However, this design is not limited to this. 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 may be provided with a snap-fit ​​hole, so that the snap-fit ​​of the first side panel 110 and the second side panel 120 can also be achieved.

[0105] In one embodiment, the slot 111 includes a connected insertion slot and a snap-fit ​​slot, the diameter of which is smaller than that of the insertion slot. The hook 121 snaps into the snap-fit ​​slot. Specifically, the slot 111 is an irregularly shaped slot, comprising a connected insertion slot and a snap-fit ​​slot. When the hook 121 snaps into the slot 111, the hook 121 first inserts into the insertion slot portion of the slot 111, and then slides into the snap-fit ​​slot portion, thereby snapping the hook 121 into the snap-fit ​​slot. The larger diameter of the insertion slot compared to the snap-fit ​​slot allows the hook 121 to easily enter the insertion slot without requiring precise alignment of the hook 121 and the slot 111 beforehand, thus improving the ease of snapping the hook 121 into the slot 111.

[0106] The diameter of the snap-fit ​​groove gradually decreases in the direction away from the insertion groove. This makes the snap-fit ​​between the hook 121 and the snap-fit ​​groove more secure, preventing the hook 121 from coming out of the snap-fit ​​groove.

[0107] In one embodiment, a hook 121 is provided on the second side panel 120. The hook 121 includes an abutting part and an anti-detaching part. The hook 121 is engaged in a snap-fit ​​groove so that the abutting part contacts the bottom wall of the snap-fit ​​groove. The anti-detaching part is located on the side of the first side panel 110 away from the second side panel 120.

[0108] Understandably, the abutting part and the anti-detachment part are arranged at an angle; in one embodiment, they are arranged in an "L" shape. When the hook 121 is engaged in the slot 111, the abutting part contacts the bottom wall of the slot, and the anti-detachment part contacts the side of the first side panel 110 opposite to the second side panel 120. The abutting part ensures that the hook 121 and the slot 111 are properly engaged, and the anti-detachment part prevents the hook 121 from coming out of the slot 111, thus preventing the connection between the first side panel 110 and the second side panel 120 from failing.

[0109] In one embodiment, the hook 121 is provided with a raised rib, which abuts against the side wall of the locking groove. Specifically, the raised rib on the hook 121 can be either protruding or recessed. When the hook 121 is engaged in the locking groove 111, the raised rib abuts against the side wall of the locking groove. The raised rib reduces the fitting accuracy between the hook 121 and the locking groove 111, and also reduces the processing difficulty of the hook 121 and the locking groove 111.

[0110] In one embodiment, both the first side panel 110 and the second side panel 120 include a panel body 171. The panel body 171 has an extension section 172 connected to one end near 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 edge of the top cover 130 abuts against the step portion 173.

[0111] Understandably, after the first side panel 110 and the second side panel 120 are joined together, the perimeter of the extension section 172 along the circumference of the cover body 102 is smaller than the perimeter of the plate body 171. Thus, when the top cover 130 is connected to the first side panel 110 and the second side panel 120, the top cover 130 covers the extension section 172, allowing the extension section 172 to extend into the top cover 130, and the edge of the top cover 130 abuts against the step portion 173. In one embodiment, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the step portion 173, that is, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the plate body 171. This is beneficial to the aesthetic appearance of the cover body 102 and the noise reduction structure.

[0112] In one embodiment, multiple extension sections 172 are provided, and the multiple extension sections 172 are spaced apart circumferentially along the cover body 102. Thus, a buffer groove 175 is formed between two adjacent extension sections 172. The buffer groove 175 allows the extension section 172 to have a certain deformation force, thereby facilitating the placement of the top cover 130 on the first side panel 110 and the second side panel 120. This reduces the fitting accuracy requirements between the top cover 130, the first side panel 110 and the second side panel 120, and improves the ease of assembly and disassembly of the top cover 130, the first side panel 110 and the second side panel 120.

[0113] In one embodiment, the extension section 172 has a guide structure at the end away from the plate body 171, and the guide structure is configured as an inwardly inclined guide flange 174. The guide flange 174 provides precise guidance for the connection between the top cover 130 and the first side panel 110 and the second side panel 120, improves the connection speed between the top cover 130 and the first side panel 110 and the second side panel 120, and improves the assembly efficiency of the cover body 102.

[0114] 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 102, the length of one of the first side panel 110 and the second side panel 120 is greater than the length of the other.

[0115] Specifically, after the first side panel 110 and the second side panel 120 are engaged, the top cover 130 is placed over the first side panel 110 and the second side panel 120. To improve the connection stability between the first side panel 110 and the top cover 130, connection holes are respectively opened on the first side panel 110 and the top cover 130, and bolts pass through the two connection holes to connect the first side panel 110 and the top cover 130. To improve the connection stability between the second side panel 120 and the top cover 130, connection holes are respectively opened on the second side panel 120 and the top cover 130, and bolts pass through the two connection holes to connect the second side panel 120 and the top cover 130. In addition, the shape and size of the first side panel 110 and the second side panel 120 can be adjusted according to the configuration of the compressor 10, and their sizes can be the same or different. In the scheme shown in the figures of this application, the length of the first side panel 110 is greater than the length of the second side panel 120 in the circumferential direction of the cover body 102. At this point, the first side panel 110 can be connected to the top cover 130 with two screws, and the second side panel 120 can be connected to the top cover 130 with one screw. After the screws are locked, the components of the entire noise reduction structure will not be able to move relative to each other, resulting in high connection strength.

[0116] Thus, the first side panel 110, the second side panel 120, and the top cover 130 are detachably connected by snap-fit, while the connection stability and reliability are improved by screw fastening. In one embodiment, the three components can be fastened with only three screws, reducing the number of screws used, saving screw fastening time, and improving assembly efficiency.

[0117] In one embodiment, the first side panel 110 is also used to screw onto the volute (not shown) of the air conditioner to improve the stability of the vibration reduction and noise reduction structure and reduce the vibration amplitude of the vibration reduction and noise reduction structure.

[0118] In one embodiment, the lower end of the cover body 102 has an opening 140, and the noise reduction structure further includes a base 160 disposed at the opening 140. The base 160 is made of an elastic element and is used for mounting the compressor 10. Thus, the provision of the elastic element helps to reduce the transmission of vibration from the compressor 10 to the outside. In one embodiment, the elastic element is made of rubber. However, this design is not limited to this; in other embodiments, the elastic element can also be made of silicone or the like.

[0119] In one embodiment, a chassis for the indoor air conditioning unit is also provided below the base 160, and the chassis is used for mounting the cover body 102. Generally, the chassis is made of plastic. The combination of the plastic chassis and the elastic base 160 can prevent and reduce the downward transmission of noise, and the elastic element helps to prevent the generation of collision vibration noise between the cover body 102 and the chassis.

[0120] In the embodiments of this application, the sound insulation layer 200 includes a first-side sound insulation layer 210, a second-side sound insulation layer 220, and a top sound insulation layer 230, which are separately disposed. The first-side sound insulation layer 210 is disposed on the inner side of the first side panel 110, the second-side sound insulation layer 220 is disposed on the inner side of the second side panel 120, and the top sound insulation layer 230 is disposed on the inner side of the top cover 130. This facilitates the installation of the cover body 102 and the sound insulation layer 200.

[0121] This application also proposes a compressor assembly, which includes a compressor 10 and a noise reduction structure. The specific structure of the noise reduction structure is as described in the above embodiments. Since this compressor assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The compressor 10 is housed in a receiving cavity 150.

[0122] This application also proposes an air conditioner, which includes a compressor assembly. The specific structure of the compressor assembly is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0123] In embodiments of this application, the air conditioner includes an indoor unit (not shown) and an outdoor unit (not shown); wherein, a compressor assembly is disposed in the indoor unit; and / or, the indoor unit and the outdoor unit are connected by a flexible refrigerant pipe (not shown), the flexible refrigerant pipe being pre-charged with refrigerant.

[0124] Air conditioner compressors generate considerable noise during operation, and a sheet metal soundproof cover is typically installed around the compressor to reduce this noise. These soundproof covers are usually quite heavy, and securing them to the plastic air conditioner chassis typically requires multiple screws. However, tightening these screws takes a considerable amount of time, resulting in low installation efficiency for the sheet metal soundproof cover.

[0125] This application proposes an air conditioner.

[0126] Please refer to Figures 8 to 12. In one embodiment of this application, the air conditioner includes a chassis 300, a compressor, and a compressor cover 100. The chassis 300 can be the chassis 300 of the indoor unit or the chassis 300 of the outdoor unit. The compressor is mounted on the chassis 300, meaning it can be installed in either the indoor or outdoor unit. The compressor cover 100 covers the compressor, housing it within a receiving cavity 150 to reduce the outward propagation of compressor system noise and reflect noise as much as possible within the compressor cover 100. In one embodiment, the entire compressor cover 100 encloses the compressor and piping. Except for the connection openings for piping and wiring, the entire structure is solid. This high sealing feature reduces the sound leakage area, preventing sound energy leakage and diffraction, thereby significantly improving the noise reduction effect.

[0127] In one embodiment, to improve noise reduction, sound-absorbing cotton is provided on the inner side of the compressor cover 100. The sound-absorbing cotton can be fixed to the compressor cover 100 using various methods such as adhesive, double-sided tape, 3M adhesive, rivet nuts, fastening straps, and screws. The sound-absorbing cotton is made of one or more of the following materials: PP / PET two-component sound-absorbing cotton, glass fiber cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, and slag wool. This application uses high-performance sound-absorbing cotton materials. The porous structure of the sound-absorbing cotton can convert sound energy into heat energy through adhesion and friction, thereby absorbing and dissipating it.

[0128] In one embodiment, to further improve the noise reduction effect, at least one compressor cover 100 and at least one layer of sound insulation cotton are provided outside the compressor, with the sound insulation cotton positioned closest to the compressor. It is understood that the compressor generates vibration and noise during operation. The main function of the sound insulation cotton is to absorb noise, and the main function of the compressor cover 100 is to seal off noise. Placing the sound insulation cotton directly close to the compressor allows for more direct and rapid noise absorption. In this application, the sound insulation cotton is made of a soft, porous, and highly sound-absorbing material. When sound waves enter the pores, they cause fiber vibration, converting sound energy into heat energy through adhesion and friction, thereby being absorbed and dissipated. The compressor cover 100 reduces the outward propagation of compressor system noise, reflecting noise as much as possible within the compressor cover 100. The compressor cover 100 is made of a dense and thick material to enhance mid-to-low frequency sound insulation and noise reduction, blocking and sealing noise within the internal space for repeated absorption by the sound insulation cotton, thus isolating it from the surrounding air.

[0129] In one embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has two layers. One layer of sound insulation cotton is used to wrap the compressor, and a compressor cover 100, another layer of sound insulation cotton, and another compressor cover 100 are sequentially arranged on its outer side. In another embodiment, the sound insulation cotton has two layers, and the compressor cover 100 has one layer. One layer of sound insulation cotton is used to wrap the compressor, and a compressor cover 100 and another layer of sound insulation cotton are sequentially arranged on its outer side; or, another layer of sound insulation cotton and a compressor cover 100 are sequentially arranged on its outer side. In yet another embodiment, the sound insulation cotton has one layer, and the compressor cover 100 has two layers. The sound insulation cotton is used to wrap the compressor, and a compressor cover 100 and another compressor cover 100 are sequentially arranged on its outer side.

[0130] In one embodiment, the compressor cover 100 is made of metal, including but 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 compressor cover 100 can be formed using sheet metal processing. It is understood that the chassis 300 of an air conditioner is generally made of plastic, and a metal compressor cover 100 is generally heavier. When connecting a heavy metal part to a plastic part, many screws are generally required for fixation, affecting assembly efficiency. In this application, the compressor cover 100 and the chassis 300 are fixed together by a snap-fit ​​connection, thereby improving the assembly efficiency of the air conditioner. Of course, the compressor cover 100 can also be made of non-metallic materials, including but not limited to one or more of ABS plastic, PP plastic, HIPS plastic, and hard rubber. A non-metallic compressor cover 100 can also be connected to the chassis 300 by a snap-fit ​​connection.

[0131] The technical solution of this application involves setting up a chassis 300, a compressor, and a compressor cover 100 in an air conditioner. The compressor is mounted on the chassis 300, and the compressor cover 100 covers the compressor and is snap-fitted to the chassis 300. Compared to the prior art, which uses multiple screws to fasten the compressor cover 100 to the chassis 300, the snap-fit ​​connection in this application eliminates the cumbersome operation of using multiple screws, saves time, and improves the assembly efficiency of the air conditioner.

[0132] In the embodiments of this application, please refer to Figures 9 and 10. One of the compressor housing 100 and the chassis 300 is provided with a pin 183, and the other is provided with a slot 310. The pin 183 engages with the slot 310. In one embodiment, the compressor housing 100 is made of metal, and the chassis 300 is made of plastic. Considering the structural strength and ease of processing of metal and plastic materials, a pin 183 can be provided on the compressor housing 100, and a slot 310 can be provided on the chassis 300. However, this design is not limited to this. In other embodiments, both the pin 183 and the slot 310 can be provided on the compressor housing 100, and corresponding slots 310 and pins 183 can be provided on the chassis 300, as long as the pin 183 and the slot 310 engage in a one-to-one correspondence. Of course, in other embodiments, one of the compressor cover 100 and the chassis 300 may be provided with a snap-fit ​​pin, and the other may be provided with a snap-fit ​​hole, with the snap-fit ​​pin snapping into the snap-fit ​​hole to connect the compressor cover 100 and the chassis 300.

[0133] Understandably, when the pin 183 is mounted on the compressor cover 100, the compressor cover 100 includes the cover body and the pin 183, wherein the pin 183 and the cover body are on the same plane. When the pin 183 is mounted on the chassis 300, the pin 183 is located at the upper end of the side wall of the chassis 300 and is on the same plane as the side wall of the chassis 300. This facilitates precise mold processing and also ensures the accuracy of the installation of the compressor cover 100 and the chassis 300.

[0134] In the embodiments of this application, please refer to Figure 11. A guide structure is provided within the slot 310. The guide structure is configured as a guide rib 320 installed on one side wall of the slot 310. The guide rib 320 extends along the depth direction of the slot 310, and a guide slope 321 is provided at one end of the guide rib 320 near the opening of the slot 310. The guide slope 321 extends obliquely towards the other side wall of the slot 310 in the depth direction. Thus, the guide structure provides precise guidance for the connection between the pin 183 and the slot 310, and also improves the engagement efficiency of the pin 183 and the slot 310.

[0135] In the scheme shown in the figures of this application, the guide structure is configured as a guide rib 320 installed in the slot 310. Along the depth direction of the slot 310, the guide rib 320 has a connected guide ramp 321 and a snap-fit ​​surface 322. Along the direction from the opening to the bottom of the slot 310, the guide ramp 321 is inclined, gradually approaching the other side wall of the slot 310. When the pin 183 needs to be snapped into the slot 310, the pin 183 aligns with the slot 310 and moves downwards. The pin 183 first contacts the guide ramp 321 and slides in along it, so that one side of the pin 183 abuts against the snap-fit ​​surface 322 of the guide rib 320. The extending direction of the snap-fit ​​surface 322 is parallel to the insertion direction of the pin 183, thus facilitating accurate insertion of the pin 183 into the slot 310. In this way, the pin 183 is snapped into the slot 310, achieving the snap-fit ​​connection between the compressor cover 100 and the chassis 300.

[0136] Multiple guide ribs 320 are provided within the slot 310, and the guide ribs 320 are spaced apart along one side wall of the slot 310 to provide more precise guidance and positioning for the insertion of the pin 183. However, this design is not limited to this; in other embodiments, the slot 310 can also be configured as a V-groove to achieve the guiding function.

[0137] In the embodiments of this application, multiple pins 183 are provided, spaced apart circumferentially along the compressor cover 100, and slots 310 are correspondingly provided with the pins 183. This arrangement of multiple pins 183 and slots 310 improves the connection stability between the compressor cover 100 and the chassis 300. With one pin 183 provided on each side of the compressor cover 100 and a corresponding slot 310 provided on the chassis 300, the balance of force on the connection between the compressor cover 100 and the chassis 300 is improved, thereby enhancing the overall structural strength of the air conditioner.

[0138] In an embodiment of this application, referring to Figure 8, the compressor cover 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. Thus, by dividing the compressor cover 100 into several spliced ​​parts, the difficulty of manufacturing the compressor cover 100 is reduced. In another embodiment, the compressor cover 100 may further include an upper end cover and side panels, wherein the side panels are cylindrical with openings at both ends, and the upper end cover is detachably connected to one opening end of the side panel. This also allows for a split configuration of the compressor cover 100, improving the efficiency of assembly and disassembly. However, this design is not limited to this; in other embodiments, the compressor cover 100 is a one-piece molded component.

[0139] In one embodiment, the first side panel 110 and the second side panel 120 are connected by a snap-fit ​​structure. This snap-fit ​​allows for quick assembly of the first side panel 110 and the second side panel 120, making the installation and removal of the compressor cover 100 easier. It also facilitates the assembly of the internal structure of the compressor cover 100, making full use of space. The efficient assembly of the compressor cover 100 also meets the high-speed production requirements of air conditioner production lines. However, this design is not limited to this. In other embodiments, the first side panel 110 and the second side panel 120 are screwed together to improve the connection stability of the first side panel 110 and the second side panel 120.

[0140] In one embodiment, referring to Figure 9, 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, the first side panel 110 is provided with a plurality of slots 111 spaced apart, and the second side panel 120 is provided with a plurality of hooks 121 spaced apart. The number and position of the slots 111 and the hooks 121 correspond. This improves the connection stability and reliability of the first side panel 110 and the second side panel 120. Of course, it is also possible to provide both slots 111 and hooks 121 on the first side panel 110, and correspondingly provide hooks 121 and slots 111 on the second side panel 120, as long as the hooks 121 and slots 111 engage one-to-one.

[0141] However, this design is not limited to this. 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 may be provided with a snap-fit ​​hole, so that the snap-fit ​​of the first side panel 110 and the second side panel 120 can also be achieved.

[0142] In one embodiment, the slot 111 includes a connected insertion slot and a snap-fit ​​slot, the diameter of which is smaller than that of the insertion slot. The hook 121 snaps into the snap-fit ​​slot. Specifically, the slot 111 is an irregularly shaped slot, comprising a connected insertion slot and a snap-fit ​​slot. When the hook 121 snaps into the slot 111, the hook 121 first inserts into the insertion slot portion of the slot 111, and then slides into the snap-fit ​​slot portion, thereby snapping the hook 121 into the snap-fit ​​slot. The larger diameter of the insertion slot compared to the snap-fit ​​slot allows the hook 121 to easily enter the insertion slot without requiring precise alignment of the hook 121 and the slot 111 beforehand, thus improving the ease of snapping the hook 121 into the slot 111.

[0143] The diameter of the snap-fit ​​groove gradually decreases in the direction away from the insertion groove. This makes the snap-fit ​​between the hook 121 and the snap-fit ​​groove more secure, preventing the hook 121 from coming out of the snap-fit ​​groove.

[0144] In one embodiment, please refer to FIG9, a hook 121 is provided on the second side panel 120. The hook 121 includes an abutment portion 122 and an anti-detachment portion 123. The hook 121 is engaged in a snap-fit ​​groove so that the abutment portion 122 contacts the bottom wall of the snap-fit ​​groove. The anti-detachment portion 123 is located on the side of the first side panel 110 away from the second side panel 120.

[0145] Understandably, the abutment portion 122 and the anti-detachment portion 123 are arranged at an angle; in one embodiment, they are arranged in an "L" shape. When the hook 121 is engaged in the slot 111, the abutment portion 122 contacts the bottom wall of the slot, and the anti-detachment portion 123 contacts the side of the first side panel 110 opposite to the second side panel 120. The abutment portion 122 ensures that the hook 121 and the slot 111 are engaged, and the anti-detachment portion 123 prevents the hook 121 from coming out of the slot 111, thus preventing the connection between the first side panel 110 and the second side panel 120 from failing.

[0146] In one embodiment, referring to Figure 9, the hook 121 is provided with a protruding rib 124, which abuts against the sidewall of the locking groove. Specifically, the protruding rib 124 on the hook 121 can be either convex or concave. When the hook 121 is engaged in the locking groove 111, the protruding rib 124 abuts against the sidewall of the locking groove. The provision of the protruding rib 124 reduces the fitting accuracy between the hook 121 and the locking groove 111, and reduces the processing difficulty of the hook 121 and the locking groove 111.

[0147] In one embodiment, referring to FIG12, both the first side panel 110 and the second side panel 120 include a panel body 171. The panel body 171 has an extension section 172 connected to one end near 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.

[0148] Understandably, after the first side panel 110 and the second side panel 120 are joined together, the perimeter of the extension section 172 along the circumference of the compressor cover 100 is smaller than the perimeter of the plate body 171. Thus, when the top cover 130 is connected to the first side panel 110 and the second side panel 120, the top cover 130 covers the extension section 172, allowing the extension section 172 to extend into the top cover 130, and the edge of the top cover 130 abuts against the step portion 173. In one embodiment, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the step portion 173, that is, the outer surface of the side wall of the top cover 130 is flush with the outer surface of the plate body 171. This is beneficial to the aesthetic appearance of the compressor cover 100 and the noise reduction structure.

[0149] In one embodiment, referring to FIG12, the extension section 172 has a guide structure at the end away from the plate body 171, and 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 side panel 110 and the second side panel 120, improves the connection speed between the top cover 130 and the first side panel 110 and the second side panel 120, and improves the assembly efficiency of the compressor cover 100.

[0150] In one embodiment, multiple guide flanges 174 are provided, and the multiple guide flanges 174 are spaced apart circumferentially along the compressor cover 100. Thus, a buffer groove 175 is formed between two adjacent guide flanges 174. The provision of the buffer groove 175 allows the guide flanges 174 to have a certain deformation force, thereby facilitating the placement of the top cover 130 on the first side panel 110 and the second side panel 120. This reduces the fitting accuracy requirements between the top cover 130, the first side panel 110 and the second side panel 120, and improves the ease of disassembly and assembly of the top cover 130, the first side panel 110 and the second side panel 120.

[0151] In one embodiment, referring to FIG8, 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 compressor cover 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.

[0152] Specifically, after the first side panel 110 and the second side panel 120 are engaged, the top cover 130 is placed over the first side panel 110 and the second side panel 120. To improve the connection stability between the first side panel 110 and the top cover 130, connection holes are respectively made on the first side panel 110 and the top cover 130, and bolts pass through the two connection holes to connect the first side panel 110 and the top cover 130. To improve the connection stability between the second side panel 120 and the top cover 130, connection holes are respectively made on the second side panel 120 and the top cover 130, and bolts pass through the two connection holes to connect the second side panel 120 and the top cover 130. In addition, the shape and size of the first side panel 110 and the second side panel 120 can be adjusted according to the configuration of the compressor; their sizes can be the same or different.

[0153] In the scheme shown in the figures of this application, the length of the first side panel 110 is greater than the length of the second side panel 120 in the circumferential direction of the compressor cover 100. The first side panel 110 can be connected to the top cover 130 with two screws, and the second side panel 120 can be connected to the top cover 130 with one screw. After the screws are locked, the components of the entire noise reduction structure cannot move relative to each other, resulting in high connection strength. At this time, pins 183 can be provided on three sides of the first side panel 110 to engage with the chassis 300; because the multiple hooks 121 of the second side panel 120 engage with the multiple slots 111 on the first side panel 110, the first side panel 110 and the second side panel 120 are connected together, and pins 183 do not need to be provided on the second side panel 120.

[0154] Thus, the first side panel 110, the second side panel 120, and the top cover 130 are detachably connected by snap-fit, while the connection stability and reliability are improved by screw fastening. In one embodiment, the three components can be fastened with only three screws, reducing the number of screws used, saving screw fastening time, and improving assembly efficiency.

[0155] In one embodiment, referring to Figure 8, the lower end of the compressor cover 100 has an opening 140. The noise reduction structure also includes a base 160 disposed at the opening 140. The base 160 is fitted onto the chassis 300, and the base 160 is made of an elastic element. The base 160 is used to mount the compressor. Thus, the elastic element helps reduce the transmission of compressor vibration to the outside. In one embodiment, the elastic element is made of rubber. However, this design is not limited to this; in other embodiments, the elastic element can also be made of silicone or the like. The plastic chassis 300 and the elastic base 160 can prevent and reduce the downward transmission of noise. The elastic element helps prevent the generation of collision vibration noise between the compressor cover 100 and the chassis 300. Furthermore, to achieve the snap-fit ​​connection between the compressor cover 100 and the chassis 300, the base 160 is provided with a clearance recess 161 for the clearance pin 183.

[0156] In one embodiment, the sound insulation cotton includes a first-side sound insulation cotton, a second-side sound insulation cotton, and a top sound insulation cotton, which are separately arranged. The first-side sound insulation cotton is located inside the first side panel 110, the second-side sound insulation cotton is located inside the second side panel 120, and the top sound insulation cotton is located inside the top cover 130. This facilitates the installation of the compressor cover 100 and the sound insulation cotton.

[0157] In an embodiment of this application, referring to Figure 8, the air conditioner further includes a duct housing 400 mounted on the chassis 300. The duct housing 400 is arranged side-by-side with the compressor cover 100, and the duct housing 400 is connected to the first side panel 110. Compared to connecting the duct housing 400 to the top cover 130, connecting the duct housing 400 to the first side panel 110 improves the connection stability between the duct housing 400 and the compressor cover 100. In one embodiment, the duct housing 400 and the first side panel 110 are detachably connected, thereby facilitating the inspection, maintenance, and replacement of the duct housing 400, the compressor cover 100, and the compressor.

[0158] In the embodiments of this application, please refer to Figure 12. A limiting bolt 410 is provided on the duct housing 400, and a limiting hole 114 is provided on the first side panel 110. The limiting bolt 410 passes through the limiting hole 114 to connect the duct housing 400 and the first side panel 110. When connecting the duct housing 400 and the first side panel 110, the limiting hole 114 is fitted outside the limiting bolt 410, thereby fixing the first side panel 110 to the duct housing 400. The limiting bolt 410, as the main force-bearing structure, can limit the compressor cover 100 in the front-back, left-right, and right directions.

[0159] In the embodiments of this application, please refer to Figure 12. The duct housing 400 has a first connecting hole 420 near the limiting bolt 410, and the first side panel 110 has a second connecting hole 115 near the limiting hole 114. A connector passes through the first connecting hole 420 and the second connecting hole 115 to connect the duct housing 400 and the first side panel 110. Specifically, to improve the connection reliability between the duct housing 400 and the compressor cover 100, the first connecting hole 420 is opened near the limiting bolt 410 on the duct housing 400, and the second connecting hole 115 is opened near the limiting hole 114 on the first side panel 110. The position of the second connecting hole 115 corresponds to the first connecting hole 420. A connector, such as a bolt, passes through the first connecting hole 420 and the second connecting hole 115 in sequence, thereby connecting the duct housing 400 and the first side panel 110 together, thereby improving the limiting stability of the compressor cover 100 in the front-back and left-right directions.

[0160] In the embodiments of this application, please refer to Figures 9 and 10. A first mounting hole 116 is provided on the first side panel 110, and a first through hole 331 is adapted to be provided on the chassis 300. A connector passes through the first mounting hole 116 and the first through hole 331 to connect the first side panel 110 and the chassis 300. A second mounting hole 125 is provided on the second side panel 120, and a second through hole 332 is adapted to be provided on the chassis 300. A connector passes through the second mounting hole 125 and the second through hole 332 to connect the second side panel 120 and the chassis 300.

[0161] Specifically, the first side panel 110 and the second side panel 120 are snapped together. The first side panel 110 is snapped together with the chassis 300 through the pin 183 and the slot 310. In order to improve the connection stability between the compressor cover 100 and the chassis 300, a screw is used to lock the first side panel 110 and the chassis 300 together, and a screw is used to lock the second side panel 120 and the chassis 300 together, thereby limiting the compressor cover 100 in the vertical direction.

[0162] In one embodiment, compared to the structure of additionally providing a flange on the compressor cover 100 and opening mounting holes on the flange, this application directly opens the first mounting hole 116 and the second mounting hole 125 on the first side panel 110 and the second side panel 120 respectively, which can achieve accurate opening and facilitate assembly and alignment with the through holes on the chassis 300. At the same time, the first through hole 331 and the second through hole 332 on the chassis 300 are both located on the side of the chassis 300, which facilitates production line operation and will not interfere with the existing structure.

[0163] When assembling the chassis 300, compressor cover 100, and duct housing 400, first install the duct housing 400 onto the chassis 300, then fit the base 160 onto the chassis 300, and then install the first side panel 110 onto the chassis 300. At this time, it is important to ensure that the limiting hole 114 on the first side panel 110 is fitted outside the limiting bolt 410 of the duct housing 400. Insert the three pins 183 at the lower end of the first side panel 110 into the three slots 310 of the chassis 300 respectively. A screw passes through the first connecting hole 420 on the duct housing 400 and the second connecting hole 115 on the first side panel 110 to lock the duct housing 400 and the first side panel 110. A screw passes through the first mounting hole 116 on the first side panel 110 and the first through hole 331 on the chassis 300 to lock the first side panel 110 and the chassis 300. Next, the second side panel 120 is snapped onto the first side panel 110, and a screw is passed through the second mounting hole 125 on the second side panel 120 and the second through hole 332 on the chassis 300 to secure the second side panel 120 and the chassis 300. Finally, the top cover 130 is placed on top of the first side panel 110 and the second side panel 120, thus completing the assembly of the chassis 300, compressor cover 100, and air duct housing 400. In this air conditioner, the connection between the components is achieved through snap-fit ​​and screw connection. Only three screws are used in the entire structure to achieve a stable and reliable connection. Compared with the method of using many screws, the number of screws used is greatly reduced, thereby reducing the screw fastening time and improving assembly efficiency.

[0164] In the embodiments of this application, please refer to Figure 8. A wire harness fixing member 190 is connected to the compressor cover 100. The wire harness fixing member 190 is used to fix the wire harness of the air conditioner. The wire harness fixing member 190 can facilitate the straightening and fixing of the wire harness in the air conditioner, facilitate the management and maintenance of the wire harness, and also contribute to the aesthetics of the wiring.

[0165] In one embodiment, the wire harness fixing member 190 is configured as a flexible metal strip. The flexible metal strip can be deformed at will to clamp the wire harness, facilitating wire harness fixation. However, this design is not limited to this; in other embodiments, the wire harness fixing member 190 may also be a strap, cable tie, etc.

[0166] In one embodiment, the flexible metal strip is wrapped with an adhesive layer on its outer side. The adhesive layer improves the usability of the wire harness fixing member 190, prevents accidental injury to the user from the flexible metal strip, and also prevents wear and tear on the wire harness caused by the flexible metal strip. In one embodiment, the adhesive layer is configured as a silicone layer, a rubber layer, or the like.

[0167] In the embodiments of this application, the air conditioner includes an indoor unit and an outdoor unit; wherein the indoor unit includes a chassis 300; and / or, the indoor unit and the outdoor unit are connected by a flexible refrigerant pipe, the flexible refrigerant pipe being pre-charged with refrigerant.

[0168] The air conditioner described in this application can be a split-type air conditioner that is easy for users to install individually. The indoor unit includes a chassis 300, on which a compressor is mounted. This means the compressor is located within the indoor unit, which reduces the weight of the outdoor unit and facilitates its installation. Correspondingly, by placing the compressor within the indoor unit, a noise reduction structure is required to ensure user comfort and low noise levels.

[0169] The air conditioner uses flexible refrigerant pipes to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when users install the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to install refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual user installation. However, this design is not limited to this; in other embodiments, the air conditioner of this application can also be a conventional split-type air conditioner.

[0170] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
