Description
Technical field
The utility model relates to a kind of hermetic compressor, especially relates to a kind of exhaust noise silencer { Dischargingnoise reducing apparatus for hermetic compressor} that the working fluid of high pressure compressed is discharged the hermetic compressor of noise minimization.
Background technique
Fig. 1 is the internal structure of common hermetic compressor.As shown in Figure 1, seal container 1 inside that is made of upper container 1t and bottom container 1b forms the space of sealing, and at above-mentioned seal space compression support 2 is installed.Be fixed with stator 3 at above-mentioned compressor seat 2,, and above-mentioned compressor seat 2 be supported on seal container 1 inside by support spring 2S by the electromagnetic action rotary crankshaft 5 of stator and rotor 4.
And bent axle 5 is installed by the central authorities of running through above-mentioned compressor seat 2, and rotor 4 one are installed on the above-mentioned bent axle 5 and by electromagnetic action and bent axle 5 rotations with said stator 3.
The cam pin 5b that is installed in above-mentioned bent axle 5 upper ends is eccentric in the rotating center of above-mentioned bent axle 5.Form equilibrium block 5c on the opposite that forms above-mentioned cam pin 5b, and form oil scavenge pump 5d, the oil duct 5a that above-mentioned oil scavenge pump 5d sucks the lubricant oil L of bottom container 1b bottom at bent axle 5 in the lower end of above-mentioned bent axle 5.
In addition, the cylinder 6 that disposes pressing chamber 6 ' is formed at one with above-mentioned compressor seat 2.And the piston 7 that is installed in above-mentioned pressing chamber 6 ' is connected with above-mentioned pressing chamber 6 ' with connecting rod 8 by the cam pin 5b of above-mentioned bent axle 5.At this moment, above-mentioned cam pin 5b is connected with the bent axle joint 8a of above-mentioned connecting rod 5b, and piston 7 then is connected by wrist pin 7 ' with the piston joint 8b of connecting rod 8.
And,, and flow into or discharge the flowing of working fluid of above-mentioned pressing chamber 6 ' by valve sets 9 control in the front end mounted valve group 9 of said cylinder 6.In above-mentioned valve sets 9 cylinder head 10 are installed, form the exhaust chamber (not shown) that the working fluid that is compressed discharge passes through.
And the inhaling silencer 11 that reduces the working fluid noise communicates by the pressing chamber 6 ' of above-mentioned valve sets 9 with cylinder 6 inside.Accompanying drawing sign 12 is the sucking pipe that working fluid is sent to seal container 1 inside, and accompanying drawing sign 13 is discharged to the outlet pipe of compressor outside for the working fluid that will compress.
The structure of the noise of the working fluid that is compressed discharge being eliminated the noise below in conjunction with Fig. 2 describes.
The exhaust passage 14 that is communicated with the exhaust chamber of above-mentioned cylinder head 10 formation is run through said cylinder body 6 and is formed, and the exhaust noise muffler unit that the working fluid that forms the discharge of above-mentioned exhaust passage 14 in a side of compressing support 2 flows into, and at above-mentioned exhaust noise muffler unit 16 covering noise muffler unit caps 17 and at inside formation anechoic room 16 ', in addition, the ring pipe 18 of discharging working fluids at above-mentioned exhaust noise muffler unit 16 runs through and is installed on above-mentioned noise muffler unit cap.
