Cavity structure of silencer in revolving type compressor

Abstract

The invention disclosed a kind of chamber body structure of silencer of rotary compressor. It includes the superior part bearing of rotation axis pressed into the center, silencer fitted over the upper part of the superior part bearing. The chamber body is formed between the superior part bearing and silencer; more than one fillister are cast on the superior part bearing-the position of the chamber body; and the fillister is corresponded to the chamber body of the silencer. Sectional area of the expending chamber is increased by changing the shape of the superior part bearing of the rotary compressor to increase the volume of the interior chamber body of silencer, so it can sharply reduce the noise valve and achieve the purpose of noise reduction. As well as, the flowing space of the refrigerant is increased to reduce the jam phenomena caused by the flowing space of refrigerant is undersize. It can improve the refrigerating capacity.

Description

technical field [0001] The present invention relates to a Background technique [0002] Traditional rotary compressor structure such as figure 1 As shown, it is composed of the following structure: a stator 7 and a rotor 8 of the motor are installed inside a housing 9 provided with a suction port 1 and an output pipe 10 and filled with a certain amount of oil; and the center of the rotor 8 is pressed into the There is a rotating shaft 6; under the rotating shaft 6, a compression part for absorbing compressed refrigerant is arranged. [0003] The compression part is composed of the following structures: a circular cylinder 3 fixed on the inner peripheral surface of the casing 9 and connected with the suction pipe; an upper bearing 4 and a lower bearing 2 that are tightly combined on both sides of the cylinder 3 and penetrate the rotating shaft 6 With the rotating shaft 6 as the center, the roller ring 11 that carries out eccentric rotation in the cylinder 3 simultaneously i...

Problems solved by technology

[0007] like figure 2 , image 3 , Figure 4 As shown, the refrigerant is discharged from the muffler 5 after being compressed by the pump body. In the existing compressor, due to the limited distance between the upper bearing 4 and the rotor 8, the design of the height of the muffler 5 is limited.

The height of muffler 5 is low, resulting in the small volume of the inner cavity of muffler 5, which is not conducive to reducing noise, resulting in low cooling capacity
