Problems solved by technology

If the piston stroke of the conventional reciprocating compressor is increased, although the influence of the clearance volume can be reduced, it will cause the compressor to rotate the crankshaft to increase, the volume of the rotating mechanism will increase, and the operating frequency of the piston will decrease and the cycle period will become longer. Eventually, it will cause a series of adverse effects such as a decrease in exhaust continuity and a large impact on the prime mover.

Abstract

The invention relates to a reciprocating compressor which comprises an air cylinder and pistons. The air cylinder comprises a cylinder body, an air cylinder inner cavity is formed in the cylinder body, and the pistons are located in the air cylinder inner cavity and can slide along the cavity wall of the air cylinder inner cavity. The pistons comprise the first piston and the second piston, and the first piston and the second piston can slide in the direction close to each other and the direction far away from each other in a reciprocating manner at the same time. According to the reciprocating compressor, the two pistons are arranged on the single air cylinder, and the two pistons move oppositely or reversely at the same time, so that the stroke of the pistons can be effectively enlarged under the condition of guaranteeing certain motion frequency of the piston. Therefore, on the basis of a certain clearance volume, the effective air suction volume can be increased, so that the volume efficiency of the air cylinder is increased, and adverse effects of the clearance volume are reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a reciprocating compressor and a household appliance provided with the reciprocating compressor. Background technique [0002] At present, due to its own structure and manufacturing process and other reasons, the impact of the residual clearance volume of the reciprocating compressor is relatively serious. Affected by the clearance volume, coupled with the limitation of the piston stroke of the reciprocating compressor, the improvement of the cylinder volume coefficient has encountered a "ceiling". If the piston stroke of the conventional reciprocating compressor is increased, although the influence of the clearance volume can be reduced, it will increase the rotation of the compressor crankshaft, increase the volume of the rotating mechanism, and cause the operating frequency of the piston to decrease and the cycle period to become longer. Eventually, it will cause a series...
