Embodiment 1

[0016] Please refer to figure 1 and figure 2 , The rotary compressor provided in this embodiment includes: a housing 11 , a cylinder 12 , an upper bearing 13 , a lower bearing 14 , a crankshaft 15 , a motor (not shown in the figure), sliding vanes 16 , and rollers 17 . The radial direction of the cylinder 12 is provided with a suction port 121 without a suction valve and an exhaust port 122 with an exhaust valve. The roller 17 is mounted on the eccentric crankshaft 15. A crescent-shaped working chamber is formed. The end of the slide 16 is in close contact with the roller 17 by the force of the spring, and the crescent-shaped working chamber is divided into two parts. The slide 16 and the roller 17 roll along the slide groove. When doing rotary motion, the upper and lower bearings 13 and 14 are placed at both ends of the cylinder 12, and form a closed cylinder volume with the inner wall of the cylinder 12, the outer wall of the roller 17, the tangent point, and the sliding p...

Embodiment 2

[0021] Please refer to image 3 , the difference from Embodiment 1 is that in the rotary compressor provided by Embodiment 2 with the function of increasing enthalpy by gas injection, the gas injection holes 211, 212 are provided on the upper bearing 13, and the upper bearing is provided with the gas injection holes 211, 212 An assembly hole is arranged above the 212 place, and the assembly hole communicates with the compressor cylinder 12 downwards through the air injection holes 211, 212. distance setting. The pipeline 22 cooperates with the air injection holes 211 and 212 provided on the upper bearing 13 through the connecting piece 23 and the sealing ring 24, so as to connect the cylinder of the compressor with the outside.

Abstract

The invention relates to a rotary compressor with enthalpy-gaining function. An upper bearing or a lower bearing of the rotary compressor is provided with one or more gas orifices; the gas orifices are matched with a pipeline so as to allow an air cylinder of the compressor to communicates with the external part of the compressor through the gas orifices; the gas orifices are provided with a one-way valve for allowing external fluid to enter the air cylinder through the pipeline and the gas orifices and preventing the fluid in the air cylinder from discharging from the gas orifices and the pipeline. The rotary compressor of the invention improves the structure of conventional rotary compressor by enabling a gaseous refrigerant to be injected into the compressor air cylinder through the pipeline, thus increasing the suction temperature of the rotary compressor, improving the compression efficiency and saving energy.

Description

technical field [0001] This invention relates to rotary compressors. Background technique [0002] Ordinary rotary compressors include cylinders, upper bearings, lower bearings, crankshafts, motors, vanes, rollers, etc. The radial direction of the cylinder is provided with a suction port without a suction valve and an exhaust port with an exhaust valve. The roller is installed on the eccentric crankshaft, and the roller rolls along the inner wall of the cylinder to form a crescent-shaped working chamber with the cylinder. The end of the slider is in close contact with the roller by the force of the spring, and the crescent-shaped working chamber is divided into two parts. The slider and the roller rotate along the groove of the slider, and the upper and lower bearings are placed in the cylinder. The upper and lower ends form a closed cylinder volume with the inner wall of the cylinder, the outer wall of the roller, the tangent point, and the sliding plate, that is, the volu...
