Muffler chamber is divided into one-level silencing and damping chamber and two grades of silencing and damping chambers, the one-level noise reduction by dividing plate, the shock resistance demarcation strip
Damping chamber is 1 with two grades of volume ratios in silencing and damping chamber:1.6, air inlet is arranged on the side lower part of muffler chamber one, silencing and damping pipe
Entrance is corresponding in one-level silencing and damping chamber with air inlet, and the outlet of silencing and damping pipe is connected with gas outlet.
And, described air inlet is broadening formation.
And, described silencing and damping pipe is arranged in muffler chamber by fixed mount.
And, described silencing and damping pipe is provided with pressure relief opening in two grades of silencing and damping chambers.
And, described pressure relief opening is symmetricly set on silencing and damping pipe for two.
And, inlet tube that described silencing and damping pipe includes being linked in sequence successively, the first reduction of speed bend pipe, the second straight tube,
3rd reduction of speed bend pipe, the 4th reduction of speed bend pipe, the 5th straight tube and outlet, between the 3rd reduction of speed bend pipe and the 4th reduction of speed bend pipe
It is provided with pressure relief opening.
The advantages of the present invention are：
1st, the freezer compressor air suction silencer of this raising gettering efficiency includes muffler chamber, silencing and damping pipe, air inlet
And gas outlet, silencing and damping pipe is arranged in muffler chamber, and shock resistance demarcation strip, the shock resistance are set in its muffler chamber
Muffler chamber is divided into one-level silencing and damping chamber and two grades of silencing and damping chambers by demarcation strip, and the one-level silencing and damping chamber disappears with two grades
The volume ratio in sound damping chamber is 1:1.6, air inlet is arranged on the side lower part of muffler chamber one, and silencing and damping tube inlet exists with air inlet
Corresponding in one-level silencing and damping chamber, the outlet of silencing and damping pipe is connected with gas outlet, and the present invention is by noise reduction inside cavity ratio
The reasonable distribution of example reaches balance pressure and reduces the effect of noise, by determining that one-level silencing and damping chamber subtracts with two grades of noise reductions
The volume ratio for shaking chamber provides space to the diameter for expanding silencing and damping pipe, the pressure loss of air-breathing is reduced, so as to improve
Efficiency.
2nd, silencing and damping pipe of the invention includes the inlet tube, the first reduction of speed bend pipe, the second straight tube, that are linked in sequence successively
Three reduction of speed bend pipes, the 4th reduction of speed bend pipe, the 5th straight tube and outlet, set between the 3rd reduction of speed bend pipe and the 4th reduction of speed bend pipe
Pressure relief opening is equipped with, the pressure relief opening is symmetricly set on silencing and damping pipe for two, silencing and damping pipe in air suction silencer of the present invention
Length and muffler chamber mating reaction, the pressure oscillation of gas and air-breathing in silencing and damping pipe during opening suction valve chip
The breakdown action of valve block coordinates more excellent, so as to suck more refrigerants, improves freezer compressor gettering efficiency.Additionally by increasing
Plus the sectional area of silencing and damping pipe mutated site and cavity, increase the area of section and accumulate ratio with pipe section, so as to have
Effect increased the penalty values that sound is transmitted from suction valve chip, reduce noise.
3rd, the present invention is by calculating the glottis neoplasms of the cavity in compressor operation frequency（100,150,200）At Hz times
Frequently, so as to reach the purpose of resonant silencing, the noise figure of harmonic wave is reduced.Meanwhile, by acoustic pressure, more refrigerants are pressed into
Cylinder, additionally increases efficiency.
4th, simple structure of the present invention, design science rationally, can effectively reduce the negative pressure in muffler chamber body, reduce compression
Machine overall noise, improves the stability of compressor.
