Sealed type compressor without baffle

Abstract

The invention discloses a sealed type compressor without baffle, which comprises a shell, wherein the shell comprises a cylindrical body, an upper cover, a lower cover and the like. A motor componentand a compressor component are arranged in the shell; the motor component comprises a stator, a rotor, a crank shaft and the like; and the compressor component comprises a cylinder, an upper bearing,a lower bearing and the like. The cylinder is arranged in the lower bearing, is matched with a protrusion of the lower bearing, and performs linear reciprocating sliding along the protrusion of the lower bearing under the driving of an eccentric part and a piston. An air suction muffler is arranged on the lower part of the lower bearing and is connected with a suction pipe. The sealed type baffle-less compressor adopts 'four-cylinder' compression and four times of compressions can be performed during each revolution of the crank shaft, so that the gas transmission capacity is increased; and without baffle, the compressor reduces the components, has less leakage, and greatly improves the reliability an the efficiency.

Description

technical field [0001] The invention belongs to a compressor, in particular to a hermetically sealed non-baffle compressor with a sliding cylinder and a rolling rotor, which can improve the efficiency of the compressor. Background technique [0002] like figure 1 , 2 As shown, the scroll piston compressor in the prior art includes a motor assembly 20 installed on the inner upper side of the casing 1, and a compressor assembly 30 installed at a certain distance on the lower side of the motor assembly 20. The casing 1 is composed of a hollow cylindrical body 11 , an upper cover 12 , a lower cover 13 and the like. The motor assembly 20 is press-fitted and fixed on the inner peripheral surface of the cylinder 11, and it is composed of a stator 21, a rotor 22, and a rotating crankshaft 23 that is press-fitted and fixed at the center of the rotor 22 and transmits rotational force. [0003] The compressor assembly 30 includes a cylinder 31, an upper bearing 32 and a lower bearin...

AI Technical Summary

Problems solved by technology

[0007] However, in the compressors of the prior art, the rolling piston is adopted, the matching accuracy of the baffle plate and the groove is high, the compression parts are many, the structure is complex, the crankshaft can only be compressed once in one rotation, and the displacement is small.

Moreover, the direct contact between the baffle and the piston is easy to scratch the contact surface of the piston, causing the contact surface of the piston to wear, resulting in gas leakage in the suction area and compression area on both sides of the baffle, reducing the exhaust volume and reducing the compressor capacity. s efficiency
