Abstract

Disclosed is a liquid storage structure of a rotary compressor. An electromotor and a compressing mechanism are arranged inside a housing of the compressor, and the electromotor is connected with a crankshaft in the compressing mechanism. The compressing mechanism comprises an air cylinder, a piston stored in the air cylinder, the crankshaft which drives the piston to rotate eccentrically through an eccentric shaft, a main bearing and a vice bearing which supports the crankshaft with the main bearing, wherein the main bearing and the vice bearing are arranged on the air cylinder, a sliding sheet slot and a suction tube mounting hole used for mounting a suction tube are arranged on the air cylinder, a liquid storage cavity is arranged inside the compressing mechanism, the liquid storage cavity is formed by one, two or all of the air cylinder, the main bearing and the vice bearing, one end of the liquid storage cavity is communicated with the suction tube, the other end of the liquid storage cavity is communicated with an air inlet of the air cylinder of the compressing mechanism, and the suction tube mounting hole and the air inlet of the air cylinder are in the same side of the sliding sheet slot. The liquid storage structure of a rotary compressor is simple and reasonable in structure, small in whole size, not only capable of effectively reducing gas suction overheating, but also achieving gas-liquid separation and reducing the quantity of gas suction overheat.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a liquid storage structure of the rotary compressor. Background technique [0002] The existing housing is a high-pressure rotary compressor, see attached figure 1 , in order to prevent liquid compression, need to be equipped with a liquid reservoir 20. Generally speaking, the accumulator should be arranged on the outer side of the rotary compressor and connected to the suction pipe of the rotary compressor. In this rotary compressor, since the accumulator is disposed outside the housing, the installation volume of the rotary compressor increases, and noise and cost due to the accumulator increase. Contents of the invention [0003] The purpose of the present invention is to provide a device with simple and reasonable structure, small overall volume, flexible operation, which can not only effectively reduce suction superheat, but also realize gas-liquid separation, reduce suction superh...
