Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a noise reduction structure and an air conditioner. Background Technology

[0002] 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. Utility Model Content

[0003] The main purpose of this utility model is to propose a noise reduction structure and an air conditioner, aiming to improve the disassembly and assembly efficiency of the noise reduction structure.

[0004] To achieve the above objectives, the noise reduction structure proposed in this utility model includes:

[0005] The compressor cover includes multiple splicing components, which enclose a receiving cavity for housing the compressor. The multiple splicing components are connected by connectors, which are separate from the splicing components.

[0006] In one embodiment, the compressor cover includes a detachably connected top cover and side panels, the side panels including a plurality of detachably connected sub-panels, adjacent sub-panels being connected by the connector.

[0007] In one embodiment, the ends of adjacent sub-panels facing the top cover are connected via the connector.

[0008] In one embodiment, the connector is provided with a first connecting groove, and at least part of the two adjacent sub-panels extend into the first connecting groove.

[0009] In one embodiment, the top cover covers the side panels and the connector.

[0010] In one embodiment, the top cover is provided with a first connecting hole, and at least one of the sub-panels is provided with a second connecting hole, the first connecting hole and the second connecting hole corresponding to each other.

[0011] In one embodiment, the top cover includes a top cover and a top sound insulation layer disposed within the top cover, and the sub-panel includes a sub-side cover and a side sound insulation layer disposed within the sub-side cover, the side sound insulation layer having a first clearance notch for avoiding the connector.

[0012] In one embodiment, one of the adjacent side sound insulation layers is provided with a second clearance for avoiding the other.

[0013] In one embodiment, the compressor cover is provided with a wire-passing notch for the wire harness to pass through; and / or

[0014] The compressor housing has a pipe opening for pipes to pass through.

[0015] This utility model also proposes an air conditioner, comprising:

[0016] Chassis;

[0017] The compressor is mounted on the chassis.

[0018] The noise reduction structure covers the compressor through the receiving cavity, and the compressor cover is inserted into the chassis.

[0019] In one embodiment, the chassis is provided with a plug-in slot, and at least a portion of the splicing components extend into the plug-in slot.

[0020] In one embodiment, the chassis includes a chassis body, on which a plug-in guide rail is provided. The plug-in guide rail includes two spaced-apart plug-in plates, and a plug-in groove is formed between the two plug-in plates.

[0021] In one embodiment, the insertion slots are provided along the circumference of the chassis.

[0022] The technical solution of this utility model involves incorporating a compressor cover within a noise reduction structure, and further dividing the compressor cover into multiple splicing components. These components are connected by connectors to form a receiving cavity for housing the compressor. The connectors and splicing components are separate entities. Compared to the existing technology where the compressor cover is a single, integrated structure, this utility model presents a split compressor cover, thereby improving the assembly and disassembly efficiency of the noise reduction structure. It allows for the removal of some splicing components at any time to observe the operation of the internal components of the compressor cover, facilitating inspection and maintenance. Simultaneously, by designing the connectors and splicing components as separate entities, compared to an integrated structure, the connectors and splicing components can be manufactured individually, reducing their processing difficulty. Furthermore, when a connector malfunctions and needs replacement, only the connector needs to be replaced, without replacing the entire splicing component, thus reducing the maintenance cost of the noise reduction structure.

[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 Figure 1 and Figure 2 In one embodiment of the present invention, the noise reduction structure includes a compressor cover 100, which includes multiple splicing parts 101. The multiple splicing parts 101 surround a receiving cavity 102, which is used to receive a compressor 400. The multiple splicing parts 101 are connected by a connector 200, and the connector 200 and the splicing parts 101 are separately arranged.

[0043] It is understandable that the compressor 400 will generate vibration and noise during operation. The compressor cover 100 is placed outside the compressor 400. The compressor cover 100 can reduce the outward transmission of the noise of the compressor 400 system and reflect the noise as much as possible inside the compressor cover 100. The compressor cover 100 is made of dense and thick materials to increase the sound insulation and noise reduction of low and medium frequencies, so as to block and seal the noise in the internal space for repeated absorption, thus isolating it from the surrounding air.

[0044] In one embodiment, the compressor cover 100 includes a cover body and a sound insulation layer connected together, with the sound insulation layer located inside the cover body. In one embodiment, the cover body can be made of damping steel plate, vibration-damping composite steel plate, hot-dip galvanized steel plate, aluminum plate, stainless steel plate, etc., or an integral structure in which damping materials (such as anti-vibration adhesive, asphalt, rubber, etc.) are coated on a sheet metal structure.

[0045] The sound insulation layer is used to encase the compressor 400. It 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 insulation layer is made of a soft, porous, 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. More specifically, the sound insulation layer can be PP / PET two-component sound insulation cotton, fiberglass cotton, non-woven fiber cotton, needle-punched felt cotton, polyester fiber cotton, rock wool, slag wool, etc., or it can be a composite material of rubber / PVC, etc., with fiber cotton / needle-punched felt and other sound-absorbing cotton (i.e., sound-absorbing cotton material coated on rubber or PVC materials).

[0046] PP refers to polypropylene, and PET refers to polyethylene terephthalate. PP / PET bicomponent sound insulation cotton is a composite material, usually made of a blend of PP and PET fibers. It combines the properties of PP and PET, possessing good elasticity and durability, and is used for sound absorption and insulation. PVC refers to polyvinyl chloride, a polymer formed by the polymerization of vinyl chloride monomer (VCM) under the action of initiators such as peroxides and azo compounds, or under the influence of light and heat, according to a free radical polymerization mechanism.

[0047] In one embodiment, the noise reduction structure may include at least one cover body and at least one sound insulation layer, thereby improving the noise reduction capability. In one embodiment, the sound insulation layer has two layers, the cover body has two layers, one sound insulation layer is used to enclose the compressor 400, and its outer side is sequentially provided with one cover body, another sound insulation layer, and another cover body. In another embodiment, the sound insulation layer has two layers, the cover body has one layer, one sound insulation layer is used to enclose the compressor 400, and its outer side is sequentially provided with one cover body and another sound insulation layer; or, its outer side is sequentially provided with another sound insulation layer and a cover body. In yet another embodiment, the sound insulation layer has one layer, the cover body has two layers, the sound insulation layer is used to enclose the compressor 400, and its outer side is sequentially provided with one cover body and another cover body. No restrictions are placed on the number of cover bodies and the arrangement order of the sound insulation layers.

[0048] However, this design is not limited to this. In other embodiments, the compressor cover 100 can also be a structure made of a material with high hardness and resistance to deformation, such as: rubber sound insulation pad, mineral wool, mineral wool board, polyurethane foam, polyurethane phenolic foam, polyester fiber board, glass wool board, polystyrene board, etc. No restrictions are placed on the number of layers or the material of the compressor cover 100.

[0049] Understandably, the compressor housing 100 is divided into multiple splicing parts 101, which are connected by connectors 200 to form a receiving cavity 102 for housing the compressor 400. Thus, compared to the prior art where the compressor housing 100 is a single unit, this invention provides a split structure for the compressor housing 100, thereby improving the efficiency of disassembly and assembly of the noise reduction structure; allowing for the removal of some splicing parts 101 at any time to observe the operation of the components inside the compressor housing 100, facilitating inspection and maintenance; furthermore, the split compressor housing 100 allows for the installation of components such as the compressor 400 within the housing through splicing, thus contributing to the miniaturization, lightweighting, and cost reduction of the compressor housing 100.

[0050] The connector 200 and the splicing component 101 are separate components; that is, in the noise reduction structure, the connector 200 is configured as a separate structure. Compared to a one-piece structure, separating the connector 200 and the splicing component 101 allows for individual fabrication of each component, reducing their processing complexity. Furthermore, if the connector 200 malfunctions and needs replacement, only the connector 200 needs to be replaced, without needing to replace the splicing component 101, thus reducing the maintenance cost of the noise reduction structure.

[0051] In one embodiment, the connector 200 is configured as a metal part, which helps to improve the structural strength of the connector 200, thereby improving the connection stability between the splicing parts 101. Of course, in other embodiments, the connector 200 can also be a plastic part. Here, there is no limitation on the material of the connector 200.

[0052] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the compressor cover 100 includes a detachably connected top cover 110 and a side panel 120. The side panel 120 includes a plurality of detachably connected sub-panels 121, and adjacent sub-panels 121 are connected by connectors 200.

[0053] Understandably, to facilitate the assembly and disassembly of the compressor cover 100, the compressor cover 100 is divided into a top cover 110 and side panels 120, wherein the side panels 120 can also be divided into multiple sub-panels 121. In the scheme shown in the figures of this utility model, there are three sub-panels 121, namely a first sub-panel 121, a second sub-panel 121, and a third sub-panel 121 connected end to end. The detachable connection between the sub-panels 121 facilitates the assembly and disassembly of the sub-panels 121 and is beneficial for the maintenance of the air conditioner. Adjacent sub-panels 121 are connected by connectors 200, that is, the first sub-panel 121 and the second sub-panel 121 are connected by connectors 200, the second sub-panel 121 and the third sub-panel 121 are connected by connectors 200, and the third sub-panel 121 and the first sub-panel 121 are connected by connectors 200. After multiple sub-panels 121 are connected by connectors 200, the top cover 110 covers the side panels 120 and connectors 200, thereby limiting the multiple splicing pieces 101 along the circumference of the compressor cover 100.

[0054] Furthermore, to limit the vertical movement of the compressor cover 100, a first connecting hole 113 is provided on the top cover 110, and a second connecting hole 126 is provided on at least one sub-panel 121, with the first connecting hole 113 and the second connecting hole 126 corresponding to each other. When the first connecting hole 113 and the second connecting hole 126 are aligned, screws, bolts, or rivets pass through the first connecting hole 113 and the second connecting hole 126, thereby connecting the top cover 110 and the sub-panel 121. In this way, while limiting the vertical movement of the compressor cover 100, the connection stability between the top cover 110 and the sub-panel 121 is also improved.

[0055] Furthermore, in one embodiment, to further improve the connection stability and reliability between the top cover 110 and the first sub-enclosure 121, a first connecting hole 113 and a second connecting hole 126 are respectively provided on the top cover 110 and the first sub-enclosure 121. Bolts and the like pass through the first connecting holes 113 and the second connecting holes 126 to connect the first sub-enclosure 121 and the top cover 110. In another embodiment, to improve the connection stability between the top cover 110 and the second sub-enclosure 121, a first connecting hole 113 and a second connecting hole 126 are respectively provided on the top cover 110 and the second sub-enclosure 121. Bolts and the like pass through the first connecting holes 113 and the second connecting holes 126 to connect the second sub-enclosure 121 and the top cover 110. In one embodiment, to improve the connection stability between the top cover 110 and the third sub-enclosure 121, a first connecting hole 113 and a second connecting hole 126 are respectively provided on the top cover 110 and the third sub-enclosure 121. Bolts or the like pass through the first connecting hole 113 and the second connecting hole 126 to connect the third sub-enclosure 121 and the top cover 110. After the top cover 110 and the sub-enclosure 121 are locked together with screws, the components of the entire noise reduction structure will not be able to move relative to each other, resulting in high connection strength. It is understood that the top cover 110 can be connected to all three sub-enclosures 121 by screws, or the top cover 110 can be connected to two of the sub-enclosures 121 by screws; no limitation is made here.

[0056] Thus, the first sub-panel 121, the second sub-panel 121, the third sub-panel 121, and the top cover 110 are detachably connected by connectors 200, while the connection stability and reliability are improved by screw fastening. In one embodiment, the top cover 110 is bolted to only two of the sub-panels 121, and the four components can be fastened with only two screws, reducing the number of screws used, saving screw fastening time, and improving assembly efficiency.

[0057] However, this design is not limited to this. In other embodiments, there may be two sub-panels 121, specifically a first sub-panel 121 and a second sub-panel 121 that are detachably connected, and the two sub-panels 121 are connected by a connector 200. Here, the number of sub-panels 121 is not limited.

[0058] Please see Figure 2 In this embodiment of the invention, the ends of adjacent sub-panels 121 facing the top cover 110 are connected by connectors 200. It is understood that the compressor cover 100 needs to be installed on the chassis 300 of the air conditioner; that is, along the height direction of the compressor cover 100, the lower ends of the sub-panels 121 are connected to the chassis 300. Thus, the sub-panels 121 can be connected together only at their upper ends by connectors 200, thereby reducing the volume of connectors 200, which is beneficial for the lightweighting of the noise reduction structure. It also helps to reduce the number of connectors 200 used and shortens the assembly time of the noise reduction structure.

[0059] However, this design is not limited to this. In one embodiment, the ends of adjacent sub-panels 121 furthest from the top cover 110 can also be connected by connectors 200. In another embodiment, adjacent sub-panels 121 are connected by a plurality of spaced-apart connectors 200 along the height direction of the compressor cover 100. In yet another embodiment, the height of the connectors 200 is the same as the height of the compressor cover 100, so that the connectors 200 connect two adjacent sub-panels 121 together. Here, the specific structure and number of connectors 200 are not limited.

[0060] Understandably, in one embodiment, two adjacent sub-panels 121 are located on different planes, that is, the connection between two adjacent sub-panels 121 is set at a corner. Correspondingly, the connector 200 is generally L-shaped, and the structural shape of the connector 200 is not limited here.

[0061] Please see Figure 2 and Figure 3 In this embodiment of the invention, the connector 200 is provided with a first connecting groove 210, and at least partially, two adjacent sub-panels 121 extend into the first connecting groove 210. Thus, by extending the sub-panels 121 into the first connecting groove 210, the connection between two adjacent sub-panels 121 is achieved. Simultaneously, overlap between adjacent sub-panels 121 is avoided, which helps reduce the material used in the side panels 120 and contributes to the lightweighting of the noise reduction structure.

[0062] However, this design is not limited to this. In other embodiments, the connector 200 can also be configured as a screw-locking structure.

[0063] In embodiments of this utility model, the top cover 110 and the side panel 120 are connected by a connector 200. It can be understood that in one embodiment, the top cover 110 and the side panel 120 are also connected by a connector 200. This reduces the assembly time required for screw fastening compared to a screw-connected top cover 110 and side panel 120 connection, thus improving assembly efficiency.

[0064] In an embodiment of this utility model, the connector 200 has a first fixing groove (not shown) and a second fixing groove (not shown) on opposite sides, and the top cover 110 and the side panel 120 extend into the first fixing groove and the second fixing groove, respectively.

[0065] Understandably, along the height direction of the compressor cover 100, the connector 200 has a first fixing groove and a second fixing groove on opposite sides, wherein the top cover 110 extends into the first fixing groove and the side panel 120 extends into the second fixing groove. More specifically, the connector 200 has an inner wall and an outer wall, with the first fixing groove and the second fixing groove formed between the inner wall and the outer wall. In one embodiment, a partition plate is provided between the first fixing groove and the second fixing groove, connecting the inner wall and the outer wall, and also separating the first fixing groove and the second fixing groove so that the first fixing groove and the second fixing groove are not connected. In another embodiment, a plurality of connecting rods are provided between the first fixing groove and the second fixing groove, with both ends of each connecting rod connected to the inner wall and the outer wall. The plurality of connecting rods realize the connection between the inner wall and the outer wall, and the gap between adjacent connecting rods also allows the first fixing groove and the second fixing groove to communicate. Here, the specific structure of the first fixing groove and the second fixing groove in the connector 200 is not limited.

[0066] Please see Figure 2 In an embodiment of the present invention, the top cover 110 includes a top cover 111 and a top sound insulation layer 112 disposed within the top cover 111, and the sub-cover 121 includes a sub-side cover 122 and a side sound insulation layer 123 disposed within the sub-side cover 122. The side sound insulation layer 123 is provided with a first clearance notch 124 for avoiding the connector 200.

[0067] Understandably, the compressor hood 100 includes a connected hood body and a sound insulation layer, with the sound insulation layer located inside the hood body. The compressor hood 100 includes a top cover 110 and a plurality of sub-enclosures 121, wherein the hood body includes a top cover 111 and sub-side covers 122, and the sound insulation layer includes a top sound insulation layer 112 and a side sound insulation layer 123. When adjacent sub-enclosures 121 are connected by connectors 200, at least a portion of the sub-enclosures 121 needs to extend into the first connecting groove 210. Generally, the sub-side covers 122 are made of a harder material, and the side sound insulation layer 123 is made of a softer material. Thus, to facilitate the extension of the sub-enclosures 121 into the first connecting groove 210, in one embodiment, only the sub-side covers 122 of the sub-enclosures 121 extend into the first connecting groove 210, and the side sound insulation layer 123 has a first clearance notch 124 at the connection position of the connector 200. This improves the connection efficiency between the sub-panel 121 and the connector 200. The shape and size of the first clearance notch 124 match the shape and size of the connector 200, and are not limited here.

[0068] Please see Figure 4 In an embodiment of this utility model, one of the two adjacent side sound insulation layers 123 is provided with a second avoidance gap 125 for avoiding the other.

[0069] Understandably, when adjacent sub-panels 121 are connected, the sub-side covers 122 of adjacent sub-panels 121 come into contact. In order to avoid interference between the side sound insulation layers 123 inside the sub-panel 121, a second clearance notch 125 is provided on one of the two adjacent side sound insulation layers 123 to avoid the other side sound insulation layer 123, thereby avoiding the warping and curling caused by interference between adjacent side sound insulation layers 123, and thus ensuring the absorption effect of compressor 400 noise.

[0070] Please see Figure 1 In an embodiment of the present invention, the compressor cover 100 is provided with a wire pass-through notch 103 for wire harnesses to pass through; and / or, the compressor cover 100 is provided with a pipe pass-through notch 104 for pipes to pass through.

[0071] Understandably, the compressor cover 100 is used to mount on the chassis 300. The compressor cover 100 has a wiring notch 103 at the end away from the chassis 300 for the wiring harness of the compressor 400 to pass through. The compressor cover 100 has a pipe notch 104 at the end near the chassis 300 for the various pipes of the compressor 400 to pass through.

[0072] In one embodiment, the entire noise reduction structure encloses the compressor 400 and piping. Except for the wire passage notch 103 and the pipe passage notch 104 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.

[0073] Please see Figure 1 and Figure 2 This utility model also proposes an air conditioner, which includes a chassis 300, a compressor 400, and a compressor cover 100. The specific structure of the compressor cover 100 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. The compressor 400 is mounted on the chassis 300; the compressor cover 100 covers the compressor 400 through a receiving cavity 102, and the compressor cover 100 is inserted into the chassis 300.

[0074] Understandably, the chassis 300 is used for mounting the compressor housing 100. Generally, the chassis 300 is made of plastic. The plastic chassis 300 can prevent and reduce the downward transmission of noise, thereby helping to reduce the operating vibration noise of the compressor 400 and improving the user comfort of the air conditioner.

[0075] In one embodiment, the lower end of the compressor housing 100 has an opening, and the noise reduction structure further includes a buffer pad disposed at the opening. The buffer pad is made of an elastic element and is used for mounting the compressor 400. Thus, the provision of the elastic element helps to reduce the transmission of vibration from the compressor 400 to the outside. In one embodiment, the buffer pad is made of rubber. However, this design is not limited to this; in other embodiments, the buffer pad can also be made of silicone or the like. Furthermore, the buffer pad between the chassis 300 and the compressor 400 also helps to prevent the generation of collision vibration noise between the compressor housing 100 and the chassis 300.

[0076] Please see Figure 2 and Figure 5 In this embodiment of the invention, the chassis 300 is provided with a insertion slot 322, and at least a portion of the splicing component 101 extends into the insertion slot 322. Thus, by inserting at least a portion of the splicing component 101 into the insertion slot 322, the connection between the splicing component 101 and the chassis 300 can be achieved, thereby facilitating the connection between the compressor cover 100 and the chassis 300. Furthermore, in this invention, there is no need to provide additional insertion structures on the splicing component 101; simply inserting a portion of the splicing component 101 into the insertion slot 322 simplifies the structure of the splicing component 101.

[0077] Please see Figure 2 and Figure 5 In an embodiment of this utility model, the chassis 300 includes a chassis body 310, and the chassis body 310 is provided with a plug-in guide rail 320. The plug-in guide rail 320 includes two plug-in plates 321 spaced apart, and a plug-in groove 322 is formed between the two plug-in plates 321.

[0078] Understandably, the chassis body 310 has a plug-in guide rail 320 at one end facing the compressor cover 100. In the embodiment shown in the figures of this utility model, the plug-in guide rail 320 is configured as two spaced-apart plug-in plates 321. Along the height direction of the compressor cover 100, the two plug-in plates 321 are parallel to each other, forming a plug-in groove 322 between them. The extending direction of the plug-in groove 322 is consistent with the extending direction of the side panel 120, thus facilitating the insertion of the side panel 120 into the plug-in groove 322. In this way, the two plug-in plates 321 provide a plug-in guide for the side panel 120 and also limit the side panel 120, preventing it from wobbling within the plug-in groove 322.

[0079] Understandably, the chassis 300 is typically made of plastic. In one embodiment, to facilitate the molding of the insertion guide 320, the insertion guide 320 is also made of plastic, so that the insertion guide 320 is integrally molded with the chassis 300. Of course, in other embodiments, the insertion guide 320 can also be made of steel, with the steel structure embedded in the chassis 300, so that it is integrally injection molded with the chassis 300. Here, the material of the insertion guide 320 is not limited.

[0080] Please see Figure 2 In one embodiment, multiple insertion slots 322 are provided along the circumference of the chassis 300. That is, multiple insertion guides 320 are provided, which helps to improve the connection stability and reliability between the splicing component 101 and the chassis 300.

[0081] In one embodiment, to further improve the connection stability and reliability of the side panel 120 and the chassis 300, through holes are provided on the side panel 120 and the chassis 300 respectively. Screws pass through the two through holes to connect the side panel 120 and the chassis 300 together, thereby improving the connection stability of the two.

[0082] However, this design is not limited to this. In other embodiments, the splicing component 101 may be provided with a slot and the chassis 300 may be provided with a pin, which is inserted into the slot to achieve the connection between the two.

[0083] In one embodiment, the air conditioner further includes an indoor unit, an outdoor unit, and a flexible connection assembly. The flexible connection assembly connects the indoor unit and the outdoor unit. This air conditioner can be a split-type air conditioner that facilitates individual installation by the user. It 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 the user installs the equipment themselves, they only need to fix the indoor and outdoor units separately, without needing to assemble refrigerant pipes or add refrigerant, thereby reducing installation difficulty and enabling individual installation.

[0084] In one embodiment, the outdoor unit of the air conditioner is mounted on the mounting medium via a mounting bracket, and the compressor 400 of the air conditioner is located in the indoor unit of the air conditioner. This reduces the weight that the mounting bracket needs to bear, thereby reducing the risk of the mounting bracket falling off.

[0085] 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. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
