Detailed Description

In order to make the above objects, features and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 9.

Example one

As shown in fig. 1 to 3, the present embodiment provides a silencer 100 for a compressor 200, where the silencer 100 mainly includes a silencing body 102 and a plurality of pipes connected to the silencing body 102, and has a simple structure, and is easy to manufacture and assemble, and specifically, the plurality of pipes are a connecting pipe 104 and a suction pipe 106. The connecting pipe 104 is disposed between the muffler body 102 and the air intake pipe 106, so that when the muffler body 102 sucks air, the fluid in the air intake pipe 106 flows to the air intake inlet 1022 of the muffler body 102 under the action of the connecting pipe 104, that is, the connecting pipe 104 plays a role of guiding the airflow, so as to reduce the disturbance of the intake fluid to the cavity in the shell of the compressor 200 where the muffler 100 is located. Specifically, the noise reduction body 102, which is a main structure for reducing noise, has a suction inlet 1022 and a noise reduction outlet, and can reduce aerodynamic noise of the fluid flowing in through the suction inlet 1022 and discharge the noise-reduced fluid to the outside through the noise reduction outlet.

The connecting pipe 104 is made of a plastic material that can be bent, plastically deformed, and has high temperature resistance and good stability.

Specifically, when applied to the compressor 200, the medium in the pipe and in the sound deadening body 102 is a refrigerant, i.e., a refrigerant. Due to the principle of compressor 200, the refrigerant in muffler body 102 is generally in a gaseous state.

Of course, since the connection pipe 104 connects the air intake pipe 106 and the silencer body 102, the air intake efficiency of the silencer body 102 can be improved, that is, the fluid flowing in through the air intake pipe 106 can flow into the silencer body 102 through the connection pipe 104, so as to improve the silencing efficiency.

In addition, when the muffler 100 is applied to the compressor 200, the fluid pressure loss of the compressor 200 during the suction operation can be effectively reduced, and the refrigerating performance can be effectively improved. Specifically, by providing the muffler 100, the flow noise of the refrigerant gas can be effectively reduced, and the volumetric efficiency of the compressor 200 can be effectively improved, which is more beneficial to the improvement of the energy efficiency of the compressor 200.

Furthermore, the connecting pipe 104 is manufactured into a straight pipe or a bent pipe according to actual use requirements, and parameters such as the direction, the radian and the length of the connecting pipe 104 are flexibly set according to actual requirements in consideration of the size of occupied space, cost and other factors.

It is understood that the fluid flowing in the suction pipe 106, the connection pipe 104 and the silencer 100 may be in a gaseous state, a liquid state or even a gas-liquid mixed state, for example, in the refrigeration field, and a refrigerant or a coolant may be used as the fluid in the fluid passage.

In a specific embodiment, the connecting tube 104 and the noise reduction body 102 are integrally formed, i.e., the noise reduction structure has higher strength.

In another specific embodiment, the connecting pipe 104 and the sound attenuating body 102 are separately processed, and then assembled after the processing, and the connection between the connecting pipe 104 and the sound attenuating body 102 may be a transition fit or an interference fit, but it is necessary to ensure the sealing of the connection between the two, for example, a sealing ring may be added, or a clamping band may be sleeved on the outer sleeve to achieve a tight sealing.

Additionally, as shown in fig. 4 and 5, the interference fit between the connection pipe 104 and the suction pipe 106 can improve the connection strength between the connection pipe 104 and the suction pipe 106, and it can be understood that the fluid in the suction pipe 106 will flow to the connection pipe 104, and the interference fit at the connection can also reduce the possibility of the fluid leaking from the connection, thereby improving the suction efficiency. Further, as shown in fig. 4, the inner diameter of the nozzle 1062 of the air suction pipe is larger than the outer diameter of the nozzle 1042 of the connection pipe, so that the air suction pipe 106 can be sleeved outside the connection pipe, thereby further reducing leakage. Of course, as shown in fig. 5, the outer diameter of the nozzle 1062 of the air suction pipe may be smaller than the inner diameter of the nozzle 1042 of the connecting pipe, so that the connecting pipe 104 is sleeved outside the air suction pipe 106, and the possibility of leakage may also be reduced.

Likewise, by defining the connection pipe 104 to be interference-fitted with the suction inlet 1022, the connection strength between the connection pipe 104 and the muffler 100 may be improved, and the suction efficiency may also be improved.

It should be noted that, depending on the relative position between the connection pipe 104 and the suction pipe 106 and the relative position between the connection pipe 104 and the suction inlet 1022, the interference fit between the connection pipe 104 and the suction pipe 106 or the suction inlet 1022 may be selected independently, or the interference fit between the two ends of the connection pipe 104 and the suction inlet 1022 may be selected simultaneously.

Example two

As shown in fig. 1 to 3, the present embodiment provides a silencer 100 for a compressor 200, the silencer 100 mainly includes a silencer body 102 and a plurality of pipes connected to the silencer body 102, and the silencer has a simple structure and is easy to process and assemble, specifically, the silencer body 102 is provided with a mounting portion 108, so that the silencer 100 can be more stable when being fixed, and the possibility of vibration of the silencer 100 during operation is reduced, and the plurality of pipes are a connecting pipe 104 and an air suction pipe 106, respectively. The connecting pipe 104 is disposed between the muffler body 102 and the air intake pipe 106, so that when the muffler body 102 sucks air, the fluid in the air intake pipe 106 flows to the air intake inlet 1022 of the muffler body 102 under the action of the connecting pipe 104, that is, the connecting pipe 104 plays a role of guiding the airflow, so as to reduce the disturbance of the intake fluid to the cavity in the shell of the compressor 200 where the muffler 100 is located. Specifically, the noise reduction body 102, which is a main structure for reducing noise, has a suction inlet 1022 and a noise reduction outlet, and can reduce aerodynamic noise of the fluid flowing in through the suction inlet 1022 and discharge the noise-reduced fluid to the outside through the noise reduction outlet.

To facilitate limiting the position of the muffler body 102, a first stopper 110 may be provided on one side of the mounting portion 108.

The position of the first stopper 110 may be any position on the mounting portion 108 as long as the first stopper 110 is connected to the mounting portion 108, and the position of the muffler body 102 is restricted by restricting the first stopper 110.

Generally, the mounting portion 108 is disposed on the top of the sound attenuating body 102, so that when the sound attenuating body 102 is fixed, the fixing can be achieved from the top by the mounting portion 108.

Of course, the number of the first limiting members 110 and the position of each first limiting member 110 may be flexibly set according to the shape or position of the silencer 100.

In a specific embodiment, as shown in fig. 2, the thickness of the first limiting member 110 is the same as that of the mounting portion 108, and is h, so that the first limiting member 110 is flush with the mounting portion 108 as a whole, and meanwhile, by limiting the width d of the first limiting member 110 to 1mm to 1.5mm, the limiting effect is achieved on the basis of reducing the dimension of the mounting portion 108 in the width direction as much as possible.

The width of the first limiting member 110 is 1mm, 1.2mm, 1.5 mm.

The connecting tube 104 is bendable, and as shown in fig. 3, the connecting tube 104 is made of a plastic material that is bendable, plastically deformable, high temperature resistant, and stable.

Specifically, when applied to the compressor 200, the medium in the pipe and in the sound deadening body 102 is a refrigerant, i.e., a refrigerant. Due to the principle of compressor 200, the refrigerant in muffler body 102 is generally in a gaseous state. Of course, since the connection pipe 104 connects the air intake pipe 106 and the silencer body 102, the air intake efficiency of the silencer body 102 can be improved, that is, the fluid flowing in through the air intake pipe 106 can flow into the silencer body 102 through the connection pipe 104, so as to improve the silencing efficiency.

Additionally, the interference fit between the connection pipe 104 and the air suction pipe 106 can improve the connection strength between the connection pipe 104 and the air suction pipe 106, and it can be understood that the fluid in the air suction pipe 106 will flow to the connection pipe 104, and the interference fit at the connection can also reduce the possibility of the fluid leaking from the connection, thereby improving the air suction efficiency. Further, the inner diameter of the nozzle of the air suction pipe 106 is larger than the outer diameter of the connection pipe, so that the air suction pipe 106 can be sleeved outside the connection pipe, thereby further reducing leakage. Of course, the outer diameter of the nozzle of the air suction pipe 106 may be smaller than the inner diameter of the connection pipe, so that the connection pipe is sleeved outside the air suction pipe 106, and the possibility of leakage reduction may also be achieved.

The suction port 206 is a structure of the compressor 200 for receiving the gas sent by the silencer 100, and the shape should match with the silencing outlet to achieve the air tightness of the air path between the gas flowing out from the silencing outlet to the suction port 206.
