Abstract

An air exhaust structure of master bearing on rotary compressor consists of shell, motor unit and compression unit. It is featured as forming ladder shaped structure with top diameter being less than diameter of bottom at shaft neck of master bearing, forming neck with diameter being greater than diameter of shaft neck at master bearing and in corresponding to shaft neck of master bearing at through hole of rotary shaft on silencer, forming cold air exhaust channel between shaft neck of master bearing and neck of silencer.

Description

technical field [0001] The present invention relates to a compressor. In particular, it relates to an exhaust structure of a main bearing of a rotary compressor that can reduce noise and improve the working efficiency of the compressor. Background technique [0002] Rotary compressors are widely used in various refrigerators and air conditioners. The rotary compressor sucks the gaseous refrigerant evaporated by the evaporator, compresses it to the saturation pressure, and then discharges it to the working system of the refrigerant. The rotary compressor can continuously A compressor that sucks in and discharges gaseous refrigerant. [0003] figure 1 is a longitudinal sectional view of a conventional rotary compressor, figure 2 yes figure 1 A magnified view of part A of the image 3 yes figure 1 Schematic diagram of the structure of the compression part, the rotor and the rotating shaft, Figure 4 yes image 3 The enlarged schematic diagram of the muffler in , Figu...
