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.

Embodiment Construction

[0021] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0022] Such as figure 1 As shown, the reciprocating compressor in this application includes a cylinder 1 , a piston 2 and a power mechanism 3 . The cylinder 1 includes a cylinder body 11, a cylinder cavity 12 is formed in the cylinder body 11, the piston 2 is located in the cylinder cavity 12, and can slide along the cavity wall of the cylinder cavity 12; The power mechanism 3 is connected with the piston 2 for driving the piston 2 to slide in the cylinder cavity 12 .

[0023] Each cylinder 1 is provided with two pistons 2, including a first piston 21 and a second piston 22; the cylinder block 11 of each cylinder 1 forms a first cylinder that cooperates with the firs...

Abstract

The invention relates to a reciprocating compressor, comprising a cylinder and a piston, the cylinder comprises a cylinder body, the piston comprises a first piston and a second piston, and the first piston and the second piston can move toward each other at the same time reciprocating sliding in the direction away from each other; the cylinder forms a first cylinder and a second cylinder respectively matched with the first piston and the second piston, and the first cylinder and the second cylinder form a certain The angular symmetry is arranged, and the tops of the first piston and the second piston are wedge-shaped. In this application, by arranging two pistons in a single cylinder, the two pistons move toward each other and oppositely at the same time, which can ensure that the piston stroke can be effectively increased under a certain movement frequency, so that the piston stroke can be increased on the basis of a certain clearance volume. , to increase the effective suction volume, thereby increasing the cylinder volume efficiency and reducing the adverse effects of the clearance volume.

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...
