Anti-falling structure and method for compressor silencer and compressor

Abstract

The invention discloses an anti-falling structure and method for a compressor silencer and a compressor, and solves the problems that in the existing technologies, the vibration frequency of the silencer is inconsistent with the vibration frequency of a machine core, so that the risk that an exhaust pipe of the silencer is broken or even falls off is easily caused, and the reliability of the compressor or even a refrigerator is affected. The invention has the beneficial effects that at least two parts of the compressor core are connected with the silencer, the support mode of a cantilever beam of the silencer is changed, and single-point support is changed into multi-point support, so that the silencer and the core synchronously vibrate, the risks of fracture and falling of the exhaust pipe of the silencer are reduced, and the reliability of the compressor is improved; according to the specific scheme, the anti-disengaging structure of a compressor silencer comprises a connecting piece connecting a compressor core and the silencer, one end of the connecting piece is connected with the compressor core, and the other end of the connecting piece is connected with the silencer.

Description

technical field [0001] The invention relates to the technical field of refrigerator compressors, in particular to a structure and method for preventing detachment of a compressor muffler and a compressor. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As the core component of the refrigerator, the compressor is the heart of the refrigerator. The refrigerator compressor generally adopts a closed rotary reciprocating compressor, and the motor drives the crank connecting rod mechanism to realize the reciprocating motion of the piston, so as to realize the suction and discharge of gas by the valve group. Due to the first-order and second-order reciprocating inertial forces of the piston, the suction valve will generate large airflow noise during the opening and closing process, so a suction muffler must be used for active noise reduction. ...

AI Technical Summary

Problems solved by technology

[0004] At present, the most commonly used muffler fixing method is the circlip connection. There is a groove for the exhaust pipe of the muffler on the cylinder head, and a circlip groove is arranged on the groove. It is found that the surroundings of the cylinder head are not closed. For the cylinder head, it is subjected to two directions of force, one is the force from four screws, which will make the cylinder head finally fixed on the cylinder block, and the other is with the force of the four screws. The force is opposite to the circlip force, and the existence of the circlip force makes the force on the cylinder head uneven. When the load demand of the refrigerator is large, the load of the compressor is large, and the exhaust pressure of the compressor is high. At this time, the cylinder head parts are prone to appear The phenomenon of high pressure leakage, resulting in a decrease in the performance of the refrigerator, and even reliability problems

[0005] In order to solve the problem of high pressure leakage, Chinese Patent Application Publication No. CN113153702A proposes a compressor cylinder head structure to prevent high pressure leakage. Support, when the compressor is energized and running, the motor drives the piston to reciprocate through the crank-connecting rod structure, the motor itself rotates at a certain speed, and the inertial force generated by the reciprocating motion of the piston causes the muffler to vibrate itself, which is related to the vibration of the movement The vibration frequency is inconsistent, so it is easy to cause the risk of the muffler exhaust pipe breaking or even falling off, thus affecting the reliability of the compressor and even the refrigerator
