[0028] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0029] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0030] As disclosed in the background section, current methods to address compressor noise during operation typically involve thickening the compressor's upper casing, altering the compressor's cavity structure, or modifying the motor structure. However, these methods are not sufficiently effective. Embodiments of this application provide a compressor that significantly reduces noise generated during operation.
[0031] Please refer to Figures 1-4 The compressor provided in the embodiments of this application includes a compressor body 100, an upper cover 200 and a sound insulation cover 300. The upper cover 200 and the sound insulation cover 300 are both disposed on the top of the compressor body 100. The sound insulation cover 300 is fixedly connected to the upper cover 200, covers the upper cover 200, and at least partially abuts against the upper cover 200.
[0032] The upper cover 200 is fixed to the top of the compressor body 100. The soundproof cover 300 is placed over the upper cover 200. Part of the soundproof cover 300 abuts against the upper cover 200. The part of the soundproof cover 300 that abuts against the upper cover 200 is fixedly connected to the upper cover 200.
[0033] By installing a soundproof cover 300 on the top of the compressor body 100 and covering the upper cover 200 with the soundproof cover 300, the soundproof cover 300 can achieve a better sound insulation effect and significantly reduce noise during compressor operation.
[0034] In this embodiment, the soundproof cover 300 is provided with a first abutting surface 310 and a second abutting surface 320 having a height difference. The first abutting surface 310 abuts against the upper cover 200, and the second abutting surface 320 abuts against the top of the compressor body 100.
[0035] The height of the first abutting surface 310 is higher than that of the second abutting surface 320. The first abutting surface 310 faces the upper cover 200 and abuts against the upper cover 200. The second abutting surface 320 faces the top of the compressor body 100 and abuts against the top of the compressor body 100.
[0036] The soundproof cover 300 is partially recessed towards the upper cover 200. The first contact surface 310 is the surface of the recessed part of the soundproof cover 300 facing the upper cover 200, and the bottom surface of the soundproof cover 300 is the second contact surface 320.
[0037] By setting a first abutting surface 310 on the soundproof cover 300 to abut against the upper cover 200 and a second abutting surface 320 to abut against the top of the compressor body 100, and then fixing the part of the soundproof cover 300 that abuts against the upper cover 200 to the upper cover 200, the soundproof cover 300 can be fixed to the upper cover 200 relatively stably.
[0038] In this embodiment, the compressor body 100 is provided with a terminal 110, the upper cover 200 is provided with a first through hole 210, and the sound insulation cover 300 is provided with a second through hole 330. The terminal 110 passes through the first through hole 210 and the second through hole 330 in sequence. The compressor also includes a terminal cover 400, which covers the terminal 110 and at least partially abuts against the sound insulation cover 300.
[0039] The second through hole 330 is opened in the recessed part of the soundproof cover 300. The opening positions of the first through hole 210 and the second through hole 330 are matched. The terminal 110 passes through the first through hole 210 and the second through hole 330 in sequence, and the terminal 110 extends out of the soundproof cover 300. The wiring cover 400 is located inside the recessed part of the soundproof cover 300 to cover the terminal 110, and the wiring cover 400 abuts against the soundproof cover 300.
[0040] It should be noted that existing compressors have a gasket between the wiring cover and the upper cover. In this embodiment, the soundproof cover 300 acts as a gasket, thus eliminating the need for the corresponding gasket in the original compressor.
[0041] In this embodiment, the compressor also includes a nut 500, and a screw 220 is provided on the upper cover 200. The screw 220 passes through the sound insulation cover 300 and the wiring cover 400 in sequence and cooperates with the nut 500.
[0042] The screw 220 extends upward from the top of the upper cover 200 along the height direction of the compressor body 100. The screw 220 passes through the recessed part of the sound insulation cover 300 and the wiring cover 400 in sequence and then extends out of the wiring cover 400. The nut 500 is threadedly engaged with the part of the screw 220 that extends out of the wiring cover 400, and the nut 500 is pressed against the wiring cover 400 to fix the wiring cover 400, the sound insulation cover 300 and the upper cover 200 relative to each other.
[0043] In other embodiments, the wiring housing cover 400 and the soundproof cover 300 may also be connected by adhesive bonding, and there is no limitation on this.
[0044] In this embodiment, the soundproof cover 300 is provided with a cylindrical body 340 with openings at both ends, and the screw 220 passes through the cylindrical body 340 and the wiring housing cover 400 and cooperates with the nut 500.
[0045] After the screw 220 passes through the first contact surface 310, the cylinder 340 and the wiring housing cover 400, it extends out of the wiring housing cover 400. During the assembly of the compressor, the setting of the cylinder 340 can facilitate the positioning of the sound insulation cover 300. By inserting the screw 220 into the cylinder 340, the sound insulation cover 300 can be quickly positioned, thereby improving assembly efficiency.
[0046] In this embodiment, the thickness t of the soundproof cover 300 is less than 30mm.
[0047] The thickness of each part of the soundproof enclosure 300 is basically the same. In actual working conditions, the thickness t of the soundproof enclosure 300 needs to be less than 30mm.
[0048] For example, the thickness t of the soundproof cover 300 is 5mm, 10mm, 15mm, 20mm or 30mm. It can be understood that the thickness t of the soundproof cover 300 can be determined according to the actual sound insulation requirements and the assembly space.
[0049] In this embodiment, the compressor satisfies: S1 / S2 < 3, where S1 is the projected area of the soundproof cover 300 along the height direction of the compressor body 100, and S2 is the projected area of the upper cover 200 along the height direction of the compressor body 100.
[0050] It should be noted that the projected area S1 of the soundproof cover 300 along the height direction of the compressor body 100 must be greater than the projected area S2 of the upper cover 200 along the height direction of the compressor body 100, so that the soundproof cover 300 can completely cover the upper cover 200.
[0051] It is understandable that the projected area S1 of the soundproof cover 300 along the height direction of the compressor body 100 and the projected area S2 of the upper cover 200 along the height direction of the compressor body 100 need to be determined according to the actual assembly requirements. Let the ratio of the projected area S1 of the soundproof cover 300 along the height direction of the compressor body 100 and the projected area S2 of the upper cover 200 along the height direction of the compressor body 100 be Q.
[0052] For example, if the assembly space around the upper cover 200 is large, the ratio Q of the projected area S1 of the sound insulation cover 300 along the height direction of the compressor body 100 to the projected area S2 of the upper cover 200 along the height direction of the compressor body 100 satisfies: 2≤Q<3; while if the assembly space around the upper cover 200 is small, the ratio Q of the projected area S1 of the sound insulation cover 300 along the height direction of the compressor body 100 to the projected area S2 of the upper cover 200 along the height direction of the compressor body 100 satisfies: 1<Q<2.
[0053] In this embodiment, the soundproof cover 300 is magnetic and is magnetically connected to the upper cover 200.
[0054] It should be noted that the soundproof cover 300 can be made of a magnetic material. When assembling the soundproof cover 300, the first contact surface 310 of the soundproof cover 300 can be magnetically connected to the upper cover 200.
[0055] In other embodiments, the soundproof cover 300 may also be connected to the upper cover 200 by adhesive bonding, and there is no limitation on this.
[0056] Furthermore, the soundproof cover 300 is made of magnetic rubber.
[0057] It should be noted that magnetic rubber, also known as magnetic rubber, is a magnetic elastomer material made of raw rubber, magnetic powder (magnetic filler), and other additives. Its magnetism comes from the filling of a large amount of magnetic powder. The soundproof cover 300 made of magnetic rubber has a certain degree of magnetism, which allows the soundproof cover 300 to be attracted to the upper shell cover 200. In order to enhance the attraction effect, more magnetic powder can be filled to enhance the magnetism.
[0058] In some alternative embodiments, the rubber is vulcanized rubber or thermoplastic rubber.
[0059] It should be noted that vulcanized rubber refers to rubber that has been vulcanized, and has properties such as not being sticky and not easily broken. Thermoplastic rubber is a type of thermoplastic soft rubber that has the elasticity of rubber but does not require vulcanization and can be directly processed into shapes (such as injection molding, extrusion, blow molding, etc.). Both vulcanized rubber and thermoplastic rubber can be filled with magnetic powder to make them magnetic.
[0060] The beneficial effects of the compressor provided in this application embodiment include at least the following: by providing a soundproof cover 300 on the top of the compressor body 100 and covering the upper cover 200 with the soundproof cover 300, the soundproof cover 300 can achieve a better sound insulation effect and significantly reduce noise during compressor operation; by providing a first abutting surface 310 on the soundproof cover 300 to abut against the upper cover 200 and a second abutting surface 320 to abut against the top of the compressor body 100, and then fixing the part of the soundproof cover 300 that abuts against the upper cover 200 to the upper cover 200, the soundproof cover 300 can be fixed to the upper cover 200 relatively stably.
[0061] refer to Figure 5 To test the sound insulation effect of the compressor in this embodiment, three compressors equipped with soundproof covers 300 were randomly selected and tested as #1, #2, and #3. The test results show that, without altering the structure of the compressor body 100, the three compressors achieved a maximum sound insulation of 51 dB in the two main frequency bands of interest, 800-2000 Hz and 3150-6300 Hz. This demonstrates that the soundproof cover 300 provides excellent sound insulation during compressor operation.
[0062] In summary, the embodiments of this application provide a compressor, which includes a compressor body 100, an upper cover 200, and a soundproof cover 300. By placing the soundproof cover 300 on top of the compressor body 100 and covering the upper cover 200, the soundproof cover 300 can effectively reduce noise during compressor operation.
[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
