Description

Technical Field

[0001] This utility model relates to the field of noise reduction equipment technology, specifically to a compressor noise reduction device. Background Technology

[0002] With the continued high temperatures of summer, abnormal noises from air conditioners have become a major concern for countless families. As the core component of an air conditioner, the compressor's malfunction can produce noticeable noises, and in 80% of cases, these noises are related to the compressor. The compressor operates by periodically completing the intake, compression, and exhaust processes. Besides the noise generated by mechanical friction, intake and exhaust also produce vibration and flow noise. This noise can be conducted to the exhaust pipe and further propagated into the indoor or surrounding environment, causing unnecessary noise pollution. The generated vibration noise can also resonate with the outdoor unit casing, amplifying the noise. Existing sound-absorbing silencers, such as the compressor intake silencer disclosed in patent publication number CN222315315U, include a cavity and a connecting pipe installed within the cavity. The cavity has an air outlet and an air inlet. The outlet end of the connecting pipe is located at the air outlet, and the wall of the outlet end has an open first heat-insulating groove along its extension direction. The inlet end of the connecting pipe is located at the air inlet, and the wall of the inlet end has an open second heat-insulating groove along its extension direction. The present invention provides an intake silencer that can reduce the heat conduction effect of the heat inside the silencer on the refrigerant entering the connecting pipe, thereby improving intake efficiency and reducing energy consumption.

[0003] However, this structure can only reduce the noise generated by the gas flow; it cannot effectively reduce or eliminate the vibration noise generated by the compressor itself or between the compressor and the casing. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the background art mentioned above and to provide a compressor silencing device. The compressor is housed and fixed in the cavity through a cavity that is tightly connected to the housing, thereby reducing the noise emitted by the compressor. A clamping mechanism is also provided between the cavity and the compressor to weaken or eliminate the vibration noise generated when the compressor is working.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a compressor silencing device, comprising a compressor, a base plate for mounting the compressor, a cavity for accommodating the compressor, and a clamping mechanism connecting the cavity and the compressor. The cavity consists of an openable upper cover and a closed wall. Its lower opening is fixedly connected to the base plate. The upper cover is also provided with a connecting hole for connecting the compressor copper pipe. The clamping mechanisms are connected in pairs to the lower and upper parts of the compressor, and the two pairs of clamping mechanisms are distributed in a cross shape around the compressor on the projection surface. The closed wall is also provided with a mounting base for connecting the clamping mechanisms.

[0006] Furthermore, the clamping mechanism includes an L-plate, which is composed of two bent surfaces and has connecting slots on both surfaces. One surface is connected to the cavity, and the other surface is connected to a top plate. A protective plate is fixedly connected to the end face of the top plate away from the cavity. The protective plate is an arc-shaped plate, and its outer wall is connected to at least two top plates. A sound-absorbing layer is connected to its inner wall.

[0007] Furthermore, the protective plate is composed of three folded plates spliced ​​together, with adjacent folded plates rotatably connected, and a top plate connected to the center of the back of each folded plate.

[0008] Furthermore, a set of horizontal or vertical mounting slots are provided on the inner wall of the protective plate, and an adhesive layer is provided in the mounting slots for bonding the sound-absorbing layer.

[0009] Furthermore, the mounting base includes a connecting column and a long strip plate. Multiple sets of connecting slots are evenly distributed on the long strip plate. The connecting column is vertically connected to the inner wall of the enclosed wall, and its other end is connected to the back of the long strip plate.

[0010] Furthermore, the enclosed wall has two airflow channels communicating with the cavity on the upper and lower sides near the radiator.

[0011] Furthermore, the two bent surfaces of the L-plate are rotatably connected by a rotating shaft.

[0012] Furthermore, the folded plates have the same arc dimensions.

[0013] The beneficial effects of this utility model are: 1) This utility model sets up a clamping mechanism to fix the compressor in the upper and lower parts of the cavity in a staggered manner. The protective plate is tightly attached to the compressor, and the sound-absorbing layer is bonded between the protective plate and the compressor, which can reduce or eliminate the vibration noise generated by the compressor. At the same time, the mounting seat is set up so that the clamping mechanism does not directly contact the cavity, which reduces the vibration transmitted to the cavity and improves the sound absorption effect. Moreover, the structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: As Figure 1-2 As shown, the compressor silencing device of this utility model includes a compressor 1, a base plate 2 for mounting the compressor 1, a cavity 3 for accommodating the compressor 1, and a clamping mechanism 4 connecting the cavity 3 and the compressor 1. The cavity 3 consists of an openable upper cover 5 and a closed wall 6. Its lower end opening is fixedly connected to the base plate 2. The upper cover 5 is also provided with a connecting hole 7 for connecting the copper pipe of the compressor 1. The connecting hole 7 is used for connecting the copper pipe to extend outward. Before installing the compressor 1, the upper cover 5 is opened and the compressor 1 is bolted to the base plate 2. Then, the closed wall 6 is fixed to the base plate 2. The clamping mechanisms 4 are connected in pairs to the lower and upper parts of the compressor 1. The two pairs of clamping mechanisms 4 are distributed in a cross shape around the compressor 1 on the projection surface. The closed wall 6 is also provided with a mounting seat 8 for connecting the clamping mechanism 4. Two airflow channels 19 connected to the cavity 3 are also opened on the upper and lower parts of the enclosed wall 6 near the external radiator. When the external radiator is working, it will drive the airflow at both ends of the airflow channel 19 to form a circulation, so that the airflow in the cavity 3 can circulate and prevent the internal heat from accumulating and causing the compressor 1 to work abnormally.

[0024] Mounting base 8 includes connecting column 17 and long strip plate 18. Multiple sets of connecting slots 10 are evenly distributed on the long strip plate 18. The connecting column 17 is vertically connected to the inner wall of the enclosed wall 6, and the other end is connected to the back of the long strip plate 18. The long strip plate 18 is installed parallel to the enclosed wall 6. When connected to L plate 9, it can be fixed at any position on the long strip plate 18 through the connecting slots 10, so that the clamping mechanism 4 can fix the compressor 1 inside the enclosed wall 6.

[0025] refer to Figure 3-5The clamping mechanism 4 includes an L-plate 9, which consists of two bent surfaces, and each bent surface has a connecting slot 10. One side is connected to the cavity 3 by bolts, and the other side is connected to a top plate 11. A protective plate 12 is fixedly connected to the end face of the top plate 11 away from the cavity 3. The protective plate 12 is an arc-shaped plate, and its outer wall is connected to the two parallel top plates 11. A set of horizontal or vertical mounting slots 15 are also provided on the inner wall of the protective plate 12. An adhesive layer 16 is provided in the mounting slots 15 for bonding the sound-absorbing layer 13.

[0026] refer to Figure 6 When connected to compressor 1, the two top plates 11 are vertically connected to the inner surface of cavity 3, pressing the protective plate 12 against the outer wall of compressor 1. At the same time, the sound-absorbing layer 13, which is made of flexible rubber, is bonded to the inner wall of the protective plate 12. When the protective plate 12 is in contact with compressor 1, the sound-absorbing layer 13 plays a role in buffering, covering and insulating sound. When the clamping mechanism 4 fixes compressor 1 in pairs, the sound-absorbing layer 13 cannot completely cover the outer wall of compressor 1. Firstly, the main source of noise of compressor 1 is the vibration noise generated during startup. Eliminating vibration does not require completely covering compressor 1; it is sufficient to cancel out the vibration. Secondly, when compressor 1 is short of refrigerant or malfunctions, it will also generate airflow noise. If compressor 1 is completely covered, the noise generated by the malfunction cannot be transmitted out, making it impossible to maintain or repair compressor 1 in time and cause it to be scrapped.

[0027] Example 2: Figure 7 The compressor 1 silencer shown is different from embodiment one in that the guard plate 12 is composed of three folded plates 14 spliced ​​together, with two adjacent folded plates 14 rotatably connected, and a top plate 11 is connected to the center of the back of each folded plate 14. The two bent surfaces of the L plate 9 are rotatably connected by a rotating shaft, and the arc dimensions of the three folded plates 14 are the same.

[0028] The back of the folding plate 14 is vertically connected to the top plate 11. The L-plate 9, which is adjustablely connected to the top plate 11, is also composed of a rotatably connected bent surface. When connected to the mounting base 8, multiple L-plates 9 are no longer limited to being connected on the same plane. By adjusting the included angle, the L-plate 9 in a clamping mechanism 4 can be simultaneously connected to the left and right sides and the front / rear sides of the cavity 3. When the size of the guard plate 12 is large, the center of its inner wall can be pressed against the outer wall of the compressor 1 by rotating the folding plate 14 to form a three-point support. The back of the folding plate 14 is fixed to the mounting base 8 by the three top plates 11 and the L-plate 9. When the folding plate 14 is bent, it will cause the sound-absorbing layer 13 to deform. However, the folding plate 14 itself is connected to the compressor 1 at three points, that is, there is a large gap between the two adjacent folding plates 14 and the compressor 1. The deformed sound-absorbing layer 13 can be piled up and filled in the gap to improve the sound absorption effect.

[0029] Similarly, the folding plate 14 can also remain in its entirety and be directly attached to the outer wall of the compressor 1 for noise reduction. Whether in the folded or integral state, the clamping mechanism 4 is installed in pairs, that is, the front and rear or left and right sides of the compressor 1 are simultaneously fixed by the clamping mechanism 4. In the height direction, the upper and lower clamping mechanisms 4 are staggered, that is, when the bottom is clamped in the front and rear, the top is clamped in the left and right, so as to reduce the vibration noise of the compressor 1 to the greatest extent.

[0030] This utility model features a clamping mechanism that fixes the compressor at the top and bottom of the cavity in a staggered manner. The protective plate is tightly fitted to the compressor, and the sound-absorbing layer is bonded between the protective plate and the compressor. This can reduce or eliminate the vibration noise generated by the compressor. At the same time, the mounting base is provided so that the clamping mechanism does not directly contact the cavity, which reduces the vibration transmitted to the cavity and improves the sound absorption effect. The structure is simple and easy to use.

[0031] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
