[0040] 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.

[0041] This utility model proposes a noise reduction structure.

[0042] Please see Figures 1 to 4In one embodiment of the present invention, the noise reduction structure includes a compressor cover 100, which has a receiving cavity 150 for accommodating a compressor (not shown). The compressor cover 100 includes a plurality of splicing parts, which surround the receiving cavity 150.

[0043] 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.

[0044] In one embodiment, sound-absorbing cotton (not shown) 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.

[0045] 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.

[0046] 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.

[0047] In this invention, 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.

[0048] The technical solution of this utility model involves setting 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, integral structure, this utility model provides a split structure for the compressor cover 100. On the one hand, the split design of the 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 design of the compressor cover 100 allows for the installation of components such as the compressor within the compressor cover 100 through splicing, thereby promoting the miniaturization, lightweighting, and cost reduction of the compressor cover 100.

[0049] Please see Figure 1 In an embodiment of this utility model, 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.

[0050] 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.

[0051] In this embodiment of the invention, 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-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 can also be detachably connected using multiple bolts.

[0052] Please see Figure 1 In an embodiment of this utility model, 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.

[0053] 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.

[0054] Please see Figure 1 and Figure 2In an embodiment of this utility model, 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.

[0055] Please see Figure 2 In this embodiment of the invention, 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.

[0056] Please see Figure 1 and Figure 3 In an embodiment of this utility model, 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 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.

[0057] 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.

[0058] Please see Figure 1 and Figure 3In this embodiment of the invention, the hook 121 is provided with a protruding rib 124, which abuts against the side wall of the locking groove 113. Specifically, the protruding rib 124 can be either convex or concave on the hook 121. When the hook 121 is engaged in the locking groove 111, the protruding rib 124 abuts against the side wall of the locking groove 113. The protruding rib 124 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.

[0059] Please see Figure 1 and Figure 4 In the embodiments of this utility model, 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.

[0060] 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.

[0061] Please see Figure 1 and Figure 4 In this embodiment of the invention, 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 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 precision requirements for the fit 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.

[0062] Please see Figure 1 and Figure 4In this embodiment of the present invention, the extension section 172 is provided with 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 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.

[0063] Please see Figure 1 In embodiments of this utility model, 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.

[0064] 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, and their sizes can be the same or different. In the embodiment shown in the figures of this utility model, 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.

[0065] 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.

[0066] Please see Figure 1In one embodiment, the lower end of the compressor housing 100 has an opening 140, and the noise reduction structure further includes a base (not shown) disposed in the opening 140. The base is made of an elastic element and is used for mounting the compressor. Thus, the elastic element helps to 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.

[0067] In one embodiment, a chassis (not shown) for the indoor unit of the air conditioner 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.

[0068] In an embodiment of this utility model, the sound insulation cotton includes a first-side sound insulation cotton (not shown), a second-side sound insulation cotton (not shown), and a top sound insulation cotton (not shown), 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.

[0069] In the embodiments of this utility model, please refer to Figure 5 The compressor cover 100 is provided with positioning ribs 180, which are used for the installation and positioning of the wiring harness fasteners. The wiring harness fasteners are used to fix the wiring harness of the air conditioner.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] This utility model also proposes a compressor assembly, which includes a compressor 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 is housed in a receiving cavity 150.

[0074] This utility model 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.

[0075] In an embodiment of this utility model, the air conditioner includes an indoor unit (not shown) and an outdoor unit (not shown); wherein, the compressor assembly is located 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.

[0076] The air conditioner of this invention can be a split-type air conditioner that is easy for users to install individually. By placing the compressor in the indoor unit, the weight of the outdoor unit can be reduced, thus facilitating its installation. Correspondingly, by placing the compressor in the indoor unit, a noise reduction structure needs to be incorporated into the compressor to ensure user comfort and low noise interference.

[0077] 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 the 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 invention can also be a conventional split-type air conditioner.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
