Air inlet mechanism of air cylinder of revolving type compressor in use for air condition

Abstract

The invention discloses an air inlet mechanism for air-conditioning rotary compressor, including: radial air inlet, vertical air channel and a rectangular air inlet channel, where the radial air inlet is a round hole radially formed on the outer wall of a compressor cylinder, the vertical air channel is a through hole penetrating two end surfaces of the cylinder and formed axially on the wall of the compressor cylinder, the rectangular air inlet is a rectangular hole formed on the inner wall of the compressor cylinder, the outer end of the radial air inlet is connected with an air inlet pipe of the compressor and the inner end connected with the vertical air channel, one side of the vertical air channel is connected with the radial air inlet and the other side connected with the rectangular air inlet, the rectangular air inlet connects the vertical air channel with an inner cavity of the compressor cylinder. Its beneficial effects: the structure is simple and easy to manufacture; it raises the compressor efficiency.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to an air intake mechanism of a rotary compressor cylinder for an air conditioner. Background technique [0002] Existing rotary compressors for air conditioners generally include: a casing, a motor, and a compression mechanism; the casing is connected to the suction pipe and the discharge pipe respectively; the motor is arranged inside the casing to provide driving force for the compression mechanism; the compression mechanism includes : a cylinder providing compression space, a rotating roller ring eccentrically arranged in the cylinder, and a partition plate that can slide up and down in the cylinder slide groove; an air-tight fit is formed between the partition plate and the roller ring and the cylinder will The cavity is divided into two parts, the compression cavity and the suction cavity; the roller ring rotates once in the cylinder under the drive of the motor, and the compression mech...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the air intake mechanism of the above-mentioned existing rotary compressor cylinder for air conditioners is that when the compressor is working, the roller ring eccentrically arranged in the cylinder rotates counterclockwise in the cylinder along the direction of the arrow shown in the figure. One stroke (that is, each rotation of the roller ring), during the period from when the roller ring leaves the edge B of the air inlet 1 to the next time it reaches point B, the cylinder suction chamber is connected to the air inlet 1, and the low-temperature and low-pressure gaseous refrigerant passes through The air inlet 1 enters the suction chamber of the cylinder; when the rolling ring contacts the edge B of the air inlet 1, the air suction chamber of the cylinder is closed, and the compressor starts to compress the low-temperature and low-pressure refrigerant entering the air suction chamber of the cylinder

[0012] The diameter of the circular air inlet 1 cannot be too small, otherwise the low-temperature and low-pressure gaseous refrigerant sucked into the cylinder suction chamber in each stroke will decrease, which will also reduce the efficiency of the compressor
