Problems solved by technology

[0004] However, in the medium gas discharged through the muffler (34), only a part of the noise generated by the pressure difference can be reduced, which is generated during the process of compressing the medium gas in the lower part of the sealed housing (10) equipped with the cylinder (31). The high frequency noise shielding effect is not good
Therefore, the high-frequency noise penetrates through the sealed housing (10) and is transmitted to the outside, thereby reducing the reliability of the product

Embodiment Construction

[0029] The shielding device for reducing the noise of the sealed rotary compressor of the present invention will be described in detail below with reference to the accompanying drawings: image 3 As shown, the noise reduction structure of the hermetic rotary compressor in the first embodiment of the present invention includes a motor (20) and a compressor assembly (30) installed in the compressor (1). The motor (20) is composed of a stator (21) and a rotor (22) installed on the upper side of the sealed casing (100), and a rotating shaft (23) that is pressed into the center of the rotor (22) and transmits rotational force, etc. . The compressor assembly (30) consists of a cylinder (31) fixed at a certain distance from the lower side of the motor (20) and installed on the upper and lower parts of the cylinder (31). While forming a compression space (C) inside the cylinder, its rotation The shaft (23) penetrates the inside of the cylinder (31) and is rotatably supported by the u...

Abstract

The invention discloses a shielding device for reducing noise of sealed rotary compressor. It includes motor stator, motor rotor and rotating shaft, cylinder combination body capable of utilizing transferred rotation force to absorb, compressor medium gas and discharge it, hollow barrel-shaped cylinder body set on the upper side and lower side of stator and upper cover and lower cover which are tightly connected with upper end and lower end of said cylinder body. Said cylinder body is made into the double-wall form or a cylindrical noise suppressor can be pressed into and fixed to the internal circumferential surface of said cylinder body so as to form the shielding space for reducing noise.

Description

[0001] Field [0002] The invention belongs to a shielding structure for reducing the noise of a sealed rotary compressor, in particular to a shielding device for reducing the noise of a sealed rotary compressor capable of reducing the noise transmitted to the outside. Background technique [0003] Such as figure 1 , 2 As shown, in the hermetic rotary compressor (1) of the prior art, a motor (20) is installed on the upper side of the sealed casing (10), and a compressor assembly (20) is installed on the lower side of the motor (20) at a certain distance 30). The sealed casing (10) is composed of a hollow cylindrical body (11), an upper cover (12) and a lower cover (13). The motor (20) is pressed and fixed on the inner peripheral surface of the cylinder (11), and it consists of a stator (21), a rotor (22) and a rotating shaft (23) which is pressed and fixed at the center of the rotor (22) and transmits the rotational force. ) and other components. The compressor assembly (...
