Piston compressor and refrigerator

Abstract

The invention provides a piston compressor and a refrigerator. The piston compressor comprises a shell and a machine core assembly, wherein the bottom of the machine core assembly is connected into the shell through a damping component; and the machine core assembly comprises an air cylinder seat. The piston compressor further comprises a first exhaust pipe and a second exhaust pipe, wherein the first exhaust pipe is provided with a first shell inner section; the second exhaust pipe is provided with a second shell inner section; the two ends of the first shell inner section are connected with an air cylinder seat and the shell respectively; the two ends of the second shell inner section are connected with the air cylinder seat and the shell respectively; the air cylinder seat is of a symmetrical structure symmetrical about a first symmetrical plane; and the first shell inner section and the second shell inner section are located on the two sides of the first symmetrical plane respectively. According to the piston compressor and the refrigerator provided by the invention, the rigidity of the exhaust pipes can be utilized to form certain supporting and limiting on the two sides of the machine core assembly, so that the vibration of the machine core assembly in the operation process and the probability of collision with the shell can be effectively reduced, the noise caused by the vibration is reduced, and the operation of the machine core assembly is more stable.

Description

technical field [0001] The invention belongs to the technical field of refrigerator design, and in particular relates to a piston compressor and a refrigerator. Background technique [0002] With the rapid development of my country's economy, household refrigerators have become an essential choice for every family. At the same time, people's living standards continue to improve, and various requirements are put forward for refrigerators such as high cooling capacity, low noise, and low vibration. [0003] The internal exhaust system of the piston compressor is related to the exhaust efficiency and exhaust noise of the compressor. It is one of the key components of the compressor. The improvement and optimization of its structure is the focus of research by various ice compressor companies. In terms of improving exhaust efficiency and reducing exhaust noise, current compressors mostly optimize the structure of the valve group. In fact, in order to reduce the compressor core (...
