Embodiment Construction
[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0023] Such as figure 1 and figure 2 As shown, the rotary compressor includes a cylinder 1 , a cylinder head 2 , a crankshaft 3 , a piston 4 and a vane 5 .
[0024] The cylinder 1 has a cylindrical chamber and an intake passage 1a communicating with the chamber. The crankshaft 3 is installed in the chamber of the cylinder 1, and the eccentric portion of the crankshaft 3 is covered with a piston 4. Usually, only a gap of less than 0.1 mm is left between the outer surface of the piston 4 and the inner surface of the cylinder 1, which not only avoids the outer surface of the piston 4 The circular surface rubs against the inner surface of the cylinder 1 to ensure the sealing. The vane 5 is embedded in the vane 5 chute of t...

The invention provides a refrigerant discharging structure of a rotary compressor, and belongs to the technical field of compressors. The rotary compressor solves the problems that when an existing rotary compressor adopts a reed type exhaust valve, the dead volume is large, and the energy efficiency ratio is affected. The refrigerant discharge structure of the rotary compressor comprises a discharge main channel positioned on a cylinder cover and a discharge chamfer channel positioned on a cylinder, wherein the discharge chamfer channel is communicated with the discharge main channel; the cylinder cover is provided with a reed type exhaust valve capable of enabling the discharge main channel to be in a cut-off state; and the discharge main channel is in a kidney shape and comprises a strip-shaped columnar area located in the middle and semi-cylindrical areas located on the two sides of the strip-shaped area. According to the rotary compressor, by adjusting the shape of the discharge main channel, the dead volume is reduced, and the machining convenience of the discharge main channel and the discharge chamfer channel is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of compressors, and relates to a rotary compressor, in particular to a refrigerant discharge structure of the rotary compressor. Background technique [0002] The rotary compressor is a motor that directly drives the rotary piston to rotate to complete the compression of the refrigerant vapor. Due to the rotary motion of the piston, the compression work is smooth, stable, and balanced. In addition, the rotary air compressor has no clearance volume and no interference from re-expansion gas, so it has high compression efficiency, fewer parts, small volume, light weight, and good balance performance. , low noise, complete protection measures and low power consumption. [0003] When the rotary compressor is running, the motor drives the crankshaft to rotate, and the piston sleeved on the eccentric part of the crankshaft rolls and moves along the inner hole wall of the cylinder. Under the elastic force of the s...
