Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an air conditioning muffler. Background Technology

[0002] An air conditioner silencer is an important component installed in an air conditioning system. Its main function is to reduce the noise generated during the operation of the air conditioner and improve the acoustic comfort of the user environment. When an air conditioner is running, the operation of components such as the compressor and fan, as well as the flow of refrigerant, all generate noise of different frequencies and intensities. The silencer reduces these noises through a specific structure and principle.

[0003] Application number CN202211569576.0 relates to a noise reduction and enhancement type air conditioner muffler. Its technical solution includes: a housing, the inner wall of which is lined with sound insulation cotton; a fixed pipe is fixedly installed on the front side inside the housing, and a purification pipe is fixedly connected to the rear side of the fixed pipe; a connecting pipe is fixedly connected to the rear side of the purification pipe, and a diversion pipe is provided on the rear side of the connecting pipe; a conduction pipe is fixedly connected to the rear side of the diversion pipe; and a ring plate is fixedly installed on the front side inside the conduction pipe.

[0004] In actual use, the above structure is inconvenient to connect and assemble with the air conditioner's connecting pipe, and it is also inconvenient to disassemble the port, making it rather inconvenient to use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides an air conditioner muffler.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner muffler, comprising a housing, a docking assembly, and a noise reduction assembly. Connecting pipes are symmetrically arranged on the left and right sides of the housing. The docking assembly includes two sets of symmetrically arranged support frames, a handle, a screw, a sliding plate, and a connecting pipe. The support frames are U-shaped, with the opening of the support frame located at an end away from the center of the housing. A handle is also provided between the two sets of support frames. Screws penetrating the support frames are symmetrically arranged on the front and rear sides of the handle. The sliding plates are arranged in two symmetrical sets, with one end of the sliding plate slidably connected to the support frame. A screw groove connected to the screw is provided on the sliding plate. The connecting pipe is sleeved on the connecting pipe, and the other end of the sliding plate is connected to the connecting pipe. The noise reduction assembly includes a sound insulation layer and a turbulence ring. A sound insulation layer is provided inside the housing, and several sets of turbulence rings are also provided inside the sound insulation layer.

[0009] To enhance the noise reduction effect, this utility model is improved by providing several sets of noise reduction grooves near the inner side of the housing of the sound insulation layer.

[0010] To facilitate stable driving of the handle, this utility model is improved by providing friction texture on the handle.

[0011] To facilitate fixing the skateboard, the present invention is improved by providing positioning components for fixing the skateboard on the left and right sides of the upper part of the housing. The positioning components include a top plate and bolts. The top plate is provided on the top wall of the support frame, and the skateboard is also provided with screw holes. The bolts are threadedly connected to the screw holes.

[0012] To ensure the sealing of the connection, the present invention is improved by providing a friction ring on the inner side of the connecting pipe, wherein the friction ring is arranged in several groups evenly.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides an air conditioner muffler with the following advantages:

[0015] This air conditioner muffler achieves its connection function through the cooperation of two sets of symmetrically arranged support frames, handles, screws, sliding plates, and connecting pipes. During operation, the connecting pipe is first fitted onto the connecting pipe of the air conditioner muffler housing. Then, the handle is turned. Because screws symmetrically arranged on both sides of the handle penetrate the support frames, and one end of the sliding plate is slidably connected to the support frame, with threaded grooves on the sliding plate for connecting to the screws, turning the handle causes the screws to rotate. This causes the sliding plate to move smoothly along the support frames under the drive of the screws, thereby adjusting the position of the connecting pipes accordingly, allowing for accurate and convenient connection to the air conditioner's piping.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An air conditioner muffler includes a housing 1, a docking assembly, and a noise reduction assembly. Connecting pipes 2 are symmetrically arranged on the left and right sides of the housing 1. The docking assembly includes two symmetrically arranged support frames 3, handles 4, screws 5, sliding plates 6, and connecting pipes 7. The support frames 3 are U-shaped, with their openings located at an end away from the center of the housing 1. A handle 4 is also provided between the two sets of support frames 3. Screws 5 are symmetrically arranged on the front and rear sides of the handle 4, penetrating the support frames 3. Two symmetrically arranged sliding plates 6 are provided, with one end slidably connected to the support frame 3 and a threaded groove on the sliding plate 6 for connection to the screws 5. The connecting pipes 7 are sleeved on the connecting pipes 2, and the other end of the sliding plate 6 is connected to the connecting pipes 7. The noise reduction assembly includes a sound insulation layer 8 and a turbulence ring 9. The sound insulation layer 8 is provided inside the housing 1, and several sets of turbulence rings 9 are also provided inside the sound insulation layer 8.

[0023] The operator grips the part of handle 4 with friction texture 10, which increases the friction between the hand and handle 4, allowing for a more stable grip. Then, by rotating handle 4, the symmetrically arranged screws 5 on both sides of handle 4 rotate synchronously. Since screws 5 pass through support frame 3, and one end of slide plate 6 is slidably connected to support frame 3, with threaded grooves matching screws 5, the rotation of screws 5 is converted into linear movement of slide plate 6 along the axial direction of screws 5 on support frame 3, according to the principle of threaded transmission. The two symmetrically arranged slide plates 6 move smoothly and simultaneously under the drive of screws 5. The other end of slide plate 6 is connected to connecting pipe 7, so the movement of slide plate 6 causes corresponding positional adjustments in connecting pipe 7. By carefully observing and appropriately rotating handle 4, the distance the slide plate 6 moves is controlled, ensuring the connecting pipe 7 is accurately aligned with the corresponding connecting pipe 2 in the air conditioning system. When the air conditioning system starts operating, noises of different frequencies and intensities generated by the compressor, fan operation, and refrigerant flow propagate towards the air conditioning muffler with the airflow. The noise first reaches the shell 1. The shell 1 itself has a certain barrier effect on the noise, blocking some external interference and reducing the outward radiation of internal noise. Subsequently, the noise enters the sound insulation layer 8 set inside the shell 1. The sound insulation layer 8 is made of materials with sound absorption and sound insulation properties (such as sound-absorbing cotton), which absorbs and reflects the incoming sound waves. When the sound energy passes through the sound insulation layer 8, it is absorbed by its internal porous structure and converted into heat or other forms of energy and consumed; the other part of the sound waves is reflected back and interferes with the subsequently incoming sound waves, further reducing the sound energy, thereby reducing the noise intensity transmitted to the subsequent structure. The remaining noise and airflow after passing through the sound insulation layer 8 continue to propagate inward and will encounter several sets of turbulence rings 9 set inside the sound insulation layer 8. The turbulence ring 9 disrupts the originally relatively stable flow of air, causing sound waves to undergo multiple reflections, refractions, and interferences within the silencer along with the turbulent airflow. Sound energy is continuously consumed in this complex process. For example, the diameter of the middle part of the shell 1 suddenly expands to form a larger cavity. Due to the sudden change in the cross-sectional area of ​​the pipe, sound waves will be reflected at the interface of different cross-sectional areas. The reflected waves interfere with the incident waves, and at a specific frequency, the sound waves can cancel each other out, thereby achieving the effect of noise reduction.

[0024] In actual use, the sound insulation layer 8 is also provided with several sets of noise reduction grooves near the inner side of the shell 1. The noise reduction grooves are honeycomb-shaped, which further enhances the noise reduction effect.

[0025] In actual use, positioning components for fixing the slide plate 6 are also provided on the left and right sides of the upper part of the housing 1. The positioning components include a top plate 11 and bolts 12. The top plate 11 is set on the top wall of the support frame 3. The slide plate 6 is also provided with screw holes. The bolts 12 are threadedly connected to the screw holes. After the connecting pipe 7 and the air conditioning pipe are accurately connected, in order to ensure that the connecting structure will not loosen or shift due to vibration or other factors during subsequent air conditioning operation, it is necessary to use the positioning components provided on the left and right sides of the upper part of the housing 1 for fixing. The positioning components consist of a top plate 11 and bolts 12. The slide plate 6 is pre-set with screw holes. The bolts 12 are passed through the top plate 11 and threadedly connected to the screw holes on the slide plate 6. By tightening the bolts 12, the top plate 11 applies pressure to the slide plate 6, fixing it in the current position and restricting the movement of the slide plate 6. This further stabilizes the connection between the connecting pipe 7 and the air conditioning connecting pipe 2, ensuring the stability of the entire connection structure and laying the foundation for the normal noise reduction function of the air conditioning muffler and the stable operation of the air conditioning system.

[0026] In this embodiment, a friction ring 13 is also provided on the inner side of the connecting pipe 7. The friction ring 13 is arranged in several groups evenly. The friction ring 13 is interference-fitted with the connecting pipe 2. The connecting pipe 7 with the friction ring 13 can be slidably connected with the connecting pipe 2. The connecting pipe 7 with the friction ring 13 is inserted into the air conditioning pipe. The friction ring 13 further ensures the sealing of its assembly.
