Abstract

According to the casing of the linear compressor of the present invention, a cylinder, a piston and a motor assembly are housed in the casing, wherein the piston reciprocates inside the cylinder, and the motor assembly is directly fastened to the The piston is used to provide a driving force to the piston; the housing is formed in a cylindrical shape; the housing is composed of a multi-layer plate formed by stacking at least two plates in the radial direction; A resonant cavity is formed on the inner surface. According to the present invention, it is also possible to reduce the amount of noise generated by a linear compressor operating at high speed, so that high-end products can be produced. Through the present invention, not only the vibration noise can be reduced, but also the sound noise can be reduced, so that the discomfort felt by consumers in various aspects can be improved. Through the present invention, the noise reduction structure of the linear compressor can be realized at low cost.

Description

technical field

[0001] The present invention relates to a linear compressor, a housing of the linear compressor and a method of manufacturing the housing. Background technique

[0002] A compressor (Compressor) is a mechanical device that compresses air, refrigerant or other gases by receiving power transmitted by a power generating device such as an electric motor or a turbine, thereby increasing the pressure. It is widely used in refrigerators, air conditioners, etc. such as household appliances or entire industries.

[0003] This kind of compressor can be roughly divided into reciprocating compressor (Reciprocating compressor), rotary compressor (Rotary compressor) and scroll compressor (Scroll compressor). There is a compression space for sucking / discharging gas between the cylinder and the cylinder, and the refrigerant is compressed by the linear reciprocating motion of the piston in the cylinder; in the rotary compressor, the eccentrically rotating roller (Roller) A ...
