Problems solved by technology

[0007] When the rotary compressor is working, the flow of gaseous refrigerant and the opening and closing of the exhaust valve will cause strong impact noise, and it has a wide frequency range, which is the main noise source of the rotary compressor. The structure of the existing muffler 80 Relatively simple, the noise reduction effect is not good, especially for the noise of special frequency bands, the noise reduction effect is even worse

Embodiment Construction

[0017] The structure of the compressor of the present invention is as shown in Figure 1: the rotary compressor has a closed casing 10, the stator 21 and the rotor 22 of the rotary compressor motor are installed on the top of the casing 10, and the eccentric shaft 30 is fixed in the middle of the rotor 22, The cylinder block 40 of the compressor is located at the bottom of the airtight casing 10, and the eccentric shaft section 31 of the eccentric shaft 30 is arranged in the cylindrical cylinder hole at the center of the cylinder block 40, and the outer cylindrical surface of the eccentric shaft section 31 has a rolling rotor, and the eccentric shaft section 31 When the eccentric shaft 30 rotates in a circular motion in the cylinder bore, the rolling rotor compresses the gaseous refrigerant entering the cylinder block 40. There is also a baffle (not shown in the figure) separating the refrigerant in the high and low pressure areas in the cylinder block. The upper and lower end s...

Abstract

The small hole type noise suppressor of rotary compressor comprises: thin wall cover shell of nois suppressor, its external form is made into a ring flat cylindrial form whose middle has hole, its interior is formed into ring hollow cavity, and its lower portion has an opening, and can be covered over the upper portion bearing, in the hole of the noise suppressor middle the shaft neck portion of upper portion bearing is passed through, and the noise suppressor is foxed on the upper portion bearing by a screw, and on the thin wall cover shell surface of the noise suppressor the air holes for eliminating noise are set. Said invention can effectively and greatly reduce noise strength.

Description

technical field [0001] The invention relates to a compressor, in particular to a small-hole muffler for a rotary compressor. Background technique [0002] Rotary compressors are widely used in various refrigerators and air conditioners. The rotary compressor sucks the gaseous refrigerant evaporated by the evaporator, compresses it to the saturation pressure, and then discharges it to the working system of the refrigerant. The rotary compressor can A compressor that continuously sucks in and discharges gaseous refrigerant. [0003] The compressor represented in Fig. 1 is a rolling rotor type rotary compressor, as can be seen from Fig. 1, the rotary compressor has a closed casing 10, and the stator 21 and the rotor 22 of the rotary compressor motor are installed on the top of the casing 10 , the eccentric shaft 30 is fixed in the middle of the rotor 22, the cylinder block 40 of the compressor is located at the bottom of the airtight casing 10, and the eccentric shaft section ...
