Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to a sound insulation structure for an air conditioning compressor. Background Technology

[0002] Air conditioner outdoor units generate noise during operation. The main sources of this noise are fan noise and compressor noise. Currently, soundproofing the compressor primarily involves wrapping it with sound-absorbing cotton and a soundproof cover.

[0003] The patent application CN22415122U, entitled "An Air Source Heat Pump and Its Compressor Sound Insulation Structure," provides a sound insulation structure for a compressor. Specifically, a layer of sound-absorbing cotton is first wrapped around the compressor's outer perimeter, and then a snap-fit ​​sound-absorbing cover is installed around the cotton. A mounting base is provided at the bottom of the sound-absorbing cover, and the compressor's bottom is fixedly mounted on this base, thus allowing the compressor to be entirely housed inside the cover for better sound insulation. While this sound insulation solution is applicable in the heat pump field, in the air conditioning outdoor unit field, because the compressor's bottom is integrated into a base plate assembly, the presence of this assembly limits the area for sound insulation cotton and the cover to the compressor's side walls and top, preventing the creation of a sound insulation solution where the entire compressor is housed inside the cover. Furthermore, the base plate assembly can also house a liquid receiver, resulting in limited space around the compressor and making it difficult to install a space-consuming sound-absorbing cover. Therefore, the sound insulation solution for the compressor disclosed in CN22415122U is not applicable to the sound insulation of the compressor in the outdoor unit of an air conditioner. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an arrangement structure suitable for air conditioner compressors, thereby achieving a sound insulation structure for air conditioner compressors.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sound insulation structure for an air conditioner compressor, including a compressor, with sound insulation cotton surrounding the outer wall of the compressor, and a sound insulation cover provided outside the sound insulation cotton, including a base plate assembly, with the bottom of the compressor fixedly mounted on the base plate assembly; the sound insulation cover includes a left sound insulation cover, a right sound insulation cover, and a sound insulation cover cap, the left and right sound insulation covers together forming a columnar shell, the sound insulation cover cap being disposed on the top of the shell, and the bottom of the shell being fixedly mounted on the base plate assembly; the compressor and the sound insulation cotton are disposed in a cavity formed by the shell, the sound insulation cover cap, and the base plate assembly.

[0006] Furthermore, the housing includes a clearance notch through which the compressor's air pipe extends to the outside of the housing; the soundproof cover includes a cover baffle extending downward along the axial direction of the housing, the soundproof cover being used to cover the clearance notch.

[0007] Furthermore, the clearance gaps include a left-side gap in the left soundproof enclosure and a right-side gap in the right soundproof enclosure.

[0008] Furthermore, the casing is prismatic.

[0009] Furthermore, the base plate assembly includes a base plate step, with the bottom of the compressor fixedly disposed on the top surface of the base plate step; it also includes a step flange disposed at the bottom of the housing, with the housing fixedly disposed on the bottom surface of the base plate step via the step flange.

[0010] Furthermore, it includes a cover edge, which includes a left edge at the bottom of the left soundproof cover and a right edge at the bottom of the right soundproof cover. The cover is fixedly mounted on the top surface of the base plate step by the cover edge.

[0011] Furthermore, it includes a first flange disposed on both sides of the left soundproof cover and a second flange disposed on both sides of the right soundproof cover. The first flange and the second flange correspond to each other and are fixed together as a single structure by fastening screws.

[0012] Furthermore, the device includes a liquid reservoir, the bottom of which is fixedly mounted on the base plate assembly, and a gap is provided between the liquid reservoir and the compressor, the width of which is greater than the thickness of the casing.

[0013] The beneficial effects of this utility model are as follows: 1. Combining the structural characteristics of the compressor integrated into the base plate assembly, the soundproof cover is designed as three parts: a left soundproof cover, a right soundproof cover, and a soundproof cover cover. The left and right soundproof covers are fastened together from the side of the compressor to form a housing, which encloses the side of the compressor. Then, the soundproof cover cover is placed over the housing from the top, thus forming a chamber composed of the housing, the soundproof cover cover, and the base plate assembly. The compressor is placed within this chamber, achieving better sound insulation. 2. Addressing the outward-extending structural characteristics of the compressor's air pipes, such as the exhaust pipe and the first intake pipe, a clearance notch is provided, allowing the air pipes to extend through the clearance notch to the outside of the housing. The clearance notch is then blocked by the cover baffle of the soundproof cover cover, reducing noise transmitted outward from the clearance notch. Third, the prism-shaped casing design effectively reduces the space occupied by the casing around the compressor. Especially when the gap between the receiver and compressor is small, the prism-shaped casing can be easily installed into the gap, completing the casing installation. Fourth, for base plate assemblies with steps, where the compressor bottom and casing bottom are located at different heights on the steps, an additional step flange is added. This allows the casing to be fixed to the bottom surface of the step via the step flange, while the compressor bottom is fixed to the top surface of the step, achieving a stable fixation. This invention is particularly suitable for sound insulation of air conditioning compressors. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 8 The air conditioner compressor sound insulation structure shown has a liquid receiver 2 and a compressor 3 fixedly mounted on the base plate assembly 1, with a gap between them. A housing formed by the left and right sound insulation covers 5 and 6, and a sound insulation cover 4 on top of the housing, encloses the compressor 3. The width of the gap between the liquid receiver 2 and the compressor 3 is greater than the thickness of the housing. The outer wall of the compressor 3 is first covered with a layer of sound insulation cotton 31. The compressor 3 and the sound insulation cotton 31 mounted on it are housed within the cavity formed by the housing, the sound insulation cover 4, and the base plate assembly 1. The compressor 3's first exhaust pipe 32, first intake pipe 33, and second intake pipe 34 extend outside the housing through pre-drilled holes in the sound insulation cotton 31 and through clearance gaps formed by the left and right notches 51 and 61, ensuring communication between the compressor 3 and the outside environment during normal operation.

[0025] Figure 6 The diagram shows one embodiment of the left soundproof cover 5. The left soundproof cover 5 is manufactured by bending sheet metal. The creases of the bends are set in the vertical direction. The sides of the left soundproof cover 5 are respectively provided with first flanges 52, the bottom edge of the left soundproof cover 5 is respectively provided with a left folded edge 54 and a stepped folded edge 7, and the bottom of the left soundproof cover 5 is provided with a wire hole 53 for passing through the corresponding electrical circuit of the compressor 3.

[0026] like Figure 7 The diagram shows one embodiment of the right soundproof cover 6. The right soundproof cover 6 is also manufactured using sheet metal bending. The creases are vertically oriented. Second flanges 62 are provided on both sides of the right soundproof cover 6, corresponding to the first flanges 52, to fasten and fix the right soundproof cover 6 and the left soundproof cover 5 together, forming a prismatic shell. Fastening screws 8 can be provided on the second flanges 62 and the first flanges 52 to secure the right soundproof cover 6 and the left soundproof cover 5 as a single unit. The bottom edge of the right soundproof cover 6 is provided with a right folded edge 63 and a stepped folded edge 7. Figure 4 As shown, the left soundproof cover 5 has a left side notch 51, and the right soundproof cover 6 has a right side notch 61. The left side notch 51 and the right side notch 61 form a clearance notch.

[0027] Figure 7 The illustration shows one embodiment of the soundproof cover 4. The soundproof cover 4 has a cover side 42 extending perpendicularly to its side. A cover baffle 41 also extends perpendicularly to the soundproof cover 4, and its length is longer than the cover side 42. In actual use, the right soundproof cover 6 and the left soundproof cover 5 are fixed together to form a shell. The inner wall of the cover side 42 engages with the outer edge of the top opening of the shell, allowing the soundproof cover 4 to be snapped onto the top of the shell. The cover baffle 41 then partially covers the clearance notch formed by the left notch 51 and the right notch 61, specifically covering the portion of the clearance notch excluding the space required for the first exhaust pipe 32, the first intake pipe 33, and the second intake pipe 34. This design is because it is necessary to prioritize ensuring that the cover baffle 41 does not interfere with the first exhaust pipe 32, the first intake pipe 33 and the second intake pipe 34 of the compressor 3. Even if the cover baffle 41 does not completely seal the clearance gap, it is within the acceptable range.

[0028] like Figures 1 to 5 As shown, the base plate assembly 1 has a recessed pleated structure to achieve greater structural strength. Specifically, the recessed pleated structure is... Figure 2 The structural form of the base plate step 11 is shown. When the compressor 3 is fixedly mounted on the base plate assembly 1, it is fixed at the top of the base plate step 11. When the cover is fixed, in addition to being fixed to the top of the base plate step 11 via the left folded edge 54 and the right folded edge 63, it is also fixed to the bottom of the base plate step 11 via the stepped folded edge 7 at the bottom of the cover. In other words, the height difference between the top and bottom surfaces of the base plate step 11 of the base plate assembly 1 is compensated by the stepped folded edge 7 at the bottom of the cover, achieving good fixation of the cover on both the top and bottom surfaces of the base plate step 11.
