Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler for an air-conditioning compressor. Background Art

[0002] The muffler reduces and attenuates the sound energy generated by the noise source through reflection, interference, absorption and other effects of the internal structure, thereby achieving the purpose of reducing noise. Due to the working environment of the air-conditioning compressor, the compressor needs to be silenced by a muffler. The muffler in the prior art generally only uses a single-structured muffler pipe for silencing, and the silencing effect is not good. Therefore, a muffler with a complex structure and good silencing effect is designed. Utility Model Content

[0003] The utility model provides an air-conditioning compressor muffler and a steam oven, solving the problem of poor muffler effect of the muffler in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] Air conditioning compressor muffler, including

[0006] A main body, wherein the interior of the main body forms a cavity;

[0007] Copper heads, set at both ends of the main body;

[0008] A silencer pipe, wherein a silencer hole is provided on the silencer pipe;

[0009] The characteristic is that at least two silencer blocks are sleeved on the silencer pipe, the silencer blocks are connected to the main body to separate the cavity into a silencer cavity and a flow cavity, the silencer cavity is communicated with the silencer hole, the silencer blocks further separate the cavity into a silencer cavity and a flow cavity, increase the flow path of the medium in the cavity, and improve the silencer efficiency, the silencer cavity is communicated with the silencer hole, so that the fluid can change the flow state multiple times when passing through, and reduce the intensity and frequency of the noise through multiple reflections and interferences, thereby further enhancing the silencer effect.

[0010] Furthermore, the silencer block is penetrated by flow holes, which connect the silencer chamber and the flow chamber. These flow holes not only connect the silencer chamber and the flow chamber, allowing the fluid to flow smoothly between the two chambers, but also further enhance the silencer effect by changing the flow path and speed of the fluid.

[0011] Furthermore, the inner surface of the flow hole is arranged in an arc shape, and the arc-shaped inner surface can also cause the fluid to generate eddy currents and turbulence when passing through the flow hole, further dispersing and weakening the energy of the noise. At the same time, the arc shape can change the flow direction of the fluid in the hole, causing the fluid to produce multiple reflections and interferences during the flow process, increasing the contact area between the fluid and the hole wall, thereby enhancing the friction and energy consumption between the fluid and the hole wall, and helping to reduce the generation of noise.

[0012] Furthermore, silencer cotton is provided on the inner surface of the silencer cavity. When noise sound waves propagate to the inner surface of the silencer cavity, the silencer cotton can effectively absorb the energy of these sound waves and convert them into heat energy or other forms of energy, thereby significantly reducing the intensity and frequency of the noise. The use of silencer cotton can also improve the service life and stability of the silencer. It can prevent the cavity wall from being directly impacted and corroded by the fluid, thereby protecting the structural integrity of the silencer.

[0013] Furthermore, two adjacent silencer blocks are connected by a connecting tube, and a threaded silencer groove is provided on the surface of the connecting tube, which can change the flow state of the fluid when passing through the connecting tube, increase the friction and collision between the fluid and the groove wall, and thus further reduce the generation of noise.

[0014] Furthermore, a through hole is provided on the silencer block, which is connected to the flow cavity and the silencer groove. When the fluid enters the silencer groove through the through hole, the threaded structure of the silencer groove can change the flow direction of the fluid, increase the contact area between the fluid and the groove wall, thereby enhancing the friction and energy consumption between the fluid and the groove wall.

[0015] Furthermore, the through holes are evenly distributed on the silencer blocks, and the through holes on the two silencer blocks are staggered. The fluid can be evenly dispersed into the through holes when passing through the silencer blocks, avoiding the formation of excessive flow velocity or eddy currents in certain specific areas, thereby reducing the noise generated by the fluid flow. The staggered arrangement of the through holes can make the fluid produce a more complex flow path when passing through adjacent silencer blocks. The staggered setting not only avoids the fluid from directly impacting the through holes of adjacent silencer blocks, reducing the generation of impact noise, but also increases the contact area between the fluid and the internal structure of the silencer, further enhancing the silencer effect.

[0016] Furthermore, an end cover is provided at one end of the silencer pipe, and a guide cavity communicated with the through hole is formed between the end cover and the silencer block. A connecting hole is provided on the end cover, and the guide cavity is communicated with the silencer hole through the connecting hole. The silenced medium can smoothly enter the silencer hole after being regulated by the guide cavity, thereby further eliminating the noise.

[0017] Furthermore, a spoiler is provided in the guide cavity. The spoiler is arranged in a fan shape and has a special streamlined structure, which can guide the fluid to form a smooth and orderly flow in the guide cavity, reduce the impact and turbulence of the fluid during the flow, and thus reduce the noise generated by the fluid flow.

[0018] Furthermore, limiting parts are provided at both ends of the main body, and both ends of the silencer pipe abut against the limiting parts. The setting of the limiting parts ensures accurate docking and stable installation between the silencer pipe and the main body.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] The utility model discloses an air-conditioning compressor silencer, and at least two silencer blocks are sleeved on the silencer pipe, and the silencer blocks are connected to the main body to separate the cavity into a silencer cavity and a flow cavity, and the silencer cavity is communicated with the silencer hole. The silencer blocks further separate the cavity into a silencer cavity and a flow cavity, thereby increasing the flow path of the medium in the cavity and improving the silencer efficiency. The silencer cavity is communicated with the silencer hole, so that the fluid can change the flow state multiple times when passing through, and the intensity and frequency of the noise are reduced by multiple reflections and interferences, thereby further enhancing the silencer effect.

[0035] like Figures 1 to 8 As shown, this is the utility model of the air-conditioning compressor silencer, the main function of which is to divide the cavity 12 into a silencer cavity 19 and a flow cavity 20 by arranging a silencer block 25 on the silencer pipe 13, thereby increasing the flow path of the medium in the cavity 12 and improving the silencer efficiency. The silencer cavity 19 is connected with the silencer hole 15, so that the fluid can change the flow state multiple times when passing through, and reduce the intensity and frequency of the noise through multiple reflections and interferences, thereby further enhancing the silencer effect.

[0036] The utility model air-conditioning compressor silencer comprises a main body 10, a silencer pipe 13 and a copper head 11. The main body 10 is cylindrical and has a cavity 12 formed inside. Limiting parts 14 are provided at the interfaces at both ends of the main body 10. The limiting parts 14 are annular end faces. The two ends of the silencer pipe 13 abut against the limiting parts 14 to facilitate the positioning and installation of the two. The matching can be completed by welding or other methods. The copper head 11 is clamped in the interfaces at both ends of the main body 10.

[0037] A silencer block 25 is installed on the silencer pipe 13. The silencer block 25 is provided with at least two pieces. The silencer block 25 can be connected to the silencer pipe 13 by welding or other connection structures with the same effect such as a limit ring. The shape of the silencer block 25 matches the inner cavity of the main body 10. The silencer block 25 is specifically annular. When the silencer block 25 is installed, the side of the silencer block 25 contacts the inner surface of the main body 10 and can be connected by means of snap connection or welding. The silencer block 25 divides the cavity 12 into at least one silencer cavity 19 and two flow cavities 20. The specific number of the silencer cavities 19 is determined according to the number of the silencer blocks 25. The silencer block 25 is penetrated by a flow hole 26. The flow holes 26 are evenly distributed along the circumference of the silencer pipe 13. The flow holes 26 connect the silencer cavity 19 and the flow cavity 20. The inner surface of the flow hole 26 is arranged in an arc shape. An arc surface 27 is formed, and the flow hole 26 includes an air inlet 28 and an air outlet 29.

The medium flows out of the silencer port and passes through the air inlet 28 and the air outlet 29 in sequence to enter the next silencer chamber 19 or the flow chamber 20. The expanded setting can slow down the flow rate of the medium and improve the silencing effect. At the same time, the arc-shaped inner surface can also cause the fluid to generate eddy currents and turbulence when passing through the flow hole 26, further dispersing and weakening the energy of the noise. At the same time, the arc shape can change the flow direction of the fluid in the hole, causing the fluid to generate multiple reflections and interferences during the flow process, increasing the contact area between the fluid and the hole wall, thereby enhancing the friction and energy consumption between the fluid and the hole wall, and helping to reduce the generation of noise.

A silencer cotton 31 is provided on the inner surface of the silencer cavity 19. When the noise sound waves propagate to the inner surface of the silencer cavity 19, the silencer cotton 31 can effectively absorb the energy of these sound waves and convert them into heat energy or other forms of energy, thereby significantly reducing the intensity and frequency of the noise. The silencer hole 15 is arranged on the silencer pipe 13 opposite to the silencer cavity 19. The surface of the connecting tube 18 is provided with a threaded silencer groove 30. A through hole 24 is circumferentially provided on the silencer block 25, and the through hole 24 is communicated with the circulation cavity 20 and the silencer groove 30. When the fluid enters the silencer groove 30 from the circulation cavity 20 through the through hole 24, the threaded structure of the silencer groove 30 can change the flow direction of the fluid, increase the contact area between the fluid and the groove wall, thereby enhancing the friction and energy consumption between the fluid and the groove wall.

[0039] An end cap 16 is provided at one end of the muffler pipe 13, and the end cap 16 is arranged at the outlet end of the muffler pipe 13. A mounting portion 23 is formed on the inner surface of the end cap 16. The mounting portion 23 is cylindrical and sleeved on the muffler pipe 13. A matching portion is formed on the surface of the end cap 16. The matching portion is annular and in close contact with the inner wall of the main body 10. A guide cavity 17 communicating with the through hole 24 is formed between the end cap 16 and the muffler block 25. A spoiler 22 is provided on the mounting portion 23. The spoiler 22 is located in the guide cavity 17. The spoiler 22 is fan-shaped and extends along the mounting portion. 23 is arranged circumferentially, and the spoiler 22 has a special streamlined structure, which can guide the fluid to form a smooth and orderly flow in the guide cavity 17, reduce the impact and turbulence of the fluid during the flow, and thus reduce the noise generated by the fluid flow.
