Rotary compressor and air conditioner with same

Abstract

The invention discloses a rotary compressor and an air conditioner with the same. The rotary compressor comprises a housing, a driver, an air cylinder, a main bearing, an auxiliary bearing, a crankshaft, a first slip sheet and a second slip sheet, wherein the driver is arranged in the housing; the air cylinder is arranged in the housing; a first slip sheet groove and a second slip sheet groove are formed in the air cylinder; the main bearing and the auxiliary bearing are arranged at the top and the bottom of the air cylinder respectively and define a chamber along with the air cylinder; the crankshaft is driven by the driver to rotate and penetrates through the main bearing and the auxiliary bearing; a piston is eccentrically sleeved on the crankshaft; the piston is rotatable relative to the crankshaft; the first slip sheet and the second slip sheet are movably arranged in the first slip sheet groove and the second slip sheet groove respectively; the inner end of the first slip sheet extends into the chamber and is connected with the piston to enable the first slip sheet to swing at a predefined angle alpha which is not smaller than -1.1*atan (e/R) and not greater than 1.1*atan (e/R); the inner end of the second slip sheet is separably matched with the outer circumferential surface of the piston. According to the rotary compressor, the efficiency of the rotary compressor is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a rotary compressor and an air conditioner with the same. Background technique [0002] In recent years, the method of controlling the air conditioning capacity and improving energy efficiency by changing the rotation speed of the motor through frequency conversion technology has become popular. However, this method has the disadvantage of increasing the number of electronic components, causing reliability problems, and increasing costs. [0003] The traditional two-cylinder variable capacity rotary compressor realizes variable capacity by controlling the working state of any cylinder. In this double-cylinder variable capacity rotary compressor, when two cylinders work at the same time, the compression is performed, which is the high-capacity mode; the compression in any one of the cylinders is interrupted to reduce the compression work, which is the low-capacity mode.

AI Technical Summary

Problems solved by technology

However, compared with the single-cylinder rotary compressor, this double-cylinder variable-displacement rotary compressor has the disadvantages of a large number of parts and high manufacturing costs. Moreover, due to the addition of a set of compression components, the friction pairs are increased, making the friction Increased loss
